The right choice depends on your jar’s mouth size, how much weight you need, and how easy the weight is to lift out after a batch is ready.

Our Picks: Best Glass Weights For Mason Jars reviews
Country Trading Co.: A Four-Pack with Wide Lift Handles
This set includes four glass weights designed for wide-mouth Mason jars. The main draw is the number of pieces: it gives you more weights on hand than any other option in this roundup, which can be useful if you ferment several jars at once or want extras ready for another batch.
Each weight has a wide handle for lifting it in and out of the jar. That can make handling easier than trying to fish a flat disc out with your fingers. The smooth glass is also described as easy to clean and sterilize before use.
The weights are intended to hold fermenting vegetables below the brine. That is their key job, but the product data does not provide a weight per piece or a diameter. Check the fit against your jar before buying if you need exact dimensions or want to compare weight with another set.
Pros:
- Four weights in one set
- Wide handles are designed for easier lifting
- Smooth glass is described as easy to clean and sterilize
- Made for wide-mouth Mason jars
Cons:
- Individual weight and diameter are not specified in the supplied product details
- The four-piece set may be more than needed for a single jar
Verdict: Choose this set if you want several weights for multiple jars and value a broad lifting handle over a published size specification.
LELELUK: Two Heavier Weights with a Defined Fit
LELELUK’s two-pack is aimed at small-batch fermentation. Each weight is listed at about 7.1 ounces, with a 2.75-inch diameter. The product details say the weights fit standard wide-mouth Mason jars in several capacities, including 16-, 24-, 32-, and 64-ounce jars.
The glass has a smooth, non-porous surface, and each weight has a grip feature for lifting it out. The stated weight and diameter make this one of the more clearly specified choices in the group, which helps if you want to compare dimensions before ordering.
It is a practical option for someone who needs a pair rather than a larger set. The tradeoff is that the pack provides only two weights, and its listed fit is for wide-mouth jars; it is not presented as a choice for regular-mouth jars.
Pros:
- Two weights, each listed at about 7.1 ounces
- 2.75-inch diameter is specified
- Designed for several sizes of wide-mouth Mason jars
- Reusable glass is described as dishwasher safe
Cons:
- Two-piece set may not cover a larger number of jars
- Designed for wide-mouth jars, not stated to fit regular-mouth jars
Verdict: Pick LELELUK if you want a two-pack with clear weight and diameter details for wide-mouth jars.
Deeriz: A Straightforward Two-Pack with Lead-Free Glass
Deeriz offers two solid glass weights with handles intended to make insertion and removal easier. They are described as made from lead-free glass for food contact and suitable for use in Mason jars and fermentation crocks.
The simple design may appeal if you want reusable weights without extra accessories. The product details say the pieces are washable and easy to maintain between batches, but do not specify a diameter, weight per piece, or dishwasher-safe status.
Compared with the LELELUK and eispap sets, Deeriz provides fewer size details. That makes it harder to confirm the fit from the listed specifications alone. If your jar opening is a close fit, check the product listing carefully before choosing this set.
Pros:
- Two-piece set with easy-grip handles
- Product details describe the glass as lead-free and suitable for food contact
- Can be used in Mason jars and fermentation crocks
- Washable glass construction
Cons:
- Weight and diameter are not provided in the supplied details
- Dishwasher safety is not specified
Verdict: Deeriz is a reasonable option if you want a basic handled pair and value the stated lead-free glass, but confirm dimensions if precise jar fit matters.
eispap: A Two-Pack with Stated Weight and Diameter
This two-piece set is designed for wide-mouth Mason jars. Each weight is listed at 7 ounces and 2.75 inches across, giving you useful dimensions to compare with your jar and other weights in this roundup.
The product description highlights a grip surface for handling and a smooth, clear glass finish. The solid glass design is intended to keep vegetables submerged, while the smooth surface is described as easy to rinse and clean after use.
Its listed size is close to the LELELUK weights, though the stated weight is slightly lower. The product information does not specify dishwasher safety or the glass’s lead-free status, so shoppers who need those details should verify them on the listing.
Pros:
- Two weights, each listed at 7 ounces
- 2.75-inch diameter is specified
- Designed for wide-mouth Mason jars
- Grip feature and smooth finish are intended to aid handling and cleanup
Cons:
- Dishwasher safety is not specified in the supplied details
- Only two weights are included
Verdict: Consider eispap if you want a clearly sized two-pack for wide-mouth jars and prefer a stated weight close to 7 ounces per piece.
Elementi: Reusable Glass Weights with Easy-Grip Handles
Elementi’s two weights are made from food-safe soda lime glass, which the product describes as non-porous and lead-free. The glass is intended not to transfer flavors or odors, and the weights are designed for keeping vegetables under the brine during fermentation.
Each piece measures 2.7 inches in diameter and is listed as compatible with Ball and other wide-mouth Mason jars. An easy-grip handle supports removal, and the product details also suggest using a fork to retrieve a weight if it sits too deep to grasp comfortably.
The weights are described as thick and heavy, but a per-piece weight is not given in the supplied information. They are listed as dishwasher safe on the top rack or suitable for handwashing. The set also has suggested uses beyond fermentation, such as pattern or sewing weights.
Pros:
- Food-safe, non-porous, lead-free glass according to the product details
- 2.7-inch diameter is specified for wide-mouth jars
- Easy-grip handles support removal
- Top-rack dishwasher safe or hand washable
Cons:
- Per-piece weight is not specified
- Two-piece set may be limited if you ferment many jars at once
Verdict: Elementi is a strong fit if you want reusable, dishwasher-safe weights with stated material details and a specified wide-mouth diameter.
How to Choose Glass Weights for Mason Jars
Check the Jar Opening
Start with the mouth size, not just the jar’s capacity. The products in this roundup are designed for wide-mouth Mason jars; the supplied details do not say that they fit regular-mouth jars. If the weight is too wide, it may not pass through the opening. If fit is uncertain, compare the product’s listed diameter with your jar before ordering.
Consider Weight and Surface Coverage
A weight’s job is to help hold fermenting vegetables under the brine. Some listings provide a per-piece weight and diameter, while others do not. If you want to compare these details directly, the LELELUK and eispap listings specify both. Keep in mind that a listed weight alone does not guarantee a particular result; how the vegetables are packed and the amount of brine also matter.
Choose a Handle You Can Remove Easily
Handles and grip features can make it easier to place or lift a glass weight, especially when it is deep inside a jar. The designs differ, so consider whether you prefer a broad handle, a molded grip, or a simpler weight that can be retrieved with a utensil if needed. Avoid assuming that every handle will be equally easy to grasp in every jar.
Match the Pack Size to Your Batch Routine
A two-pack suits someone who usually prepares one or two jars at a time. A four-pack, like the Country Trading Co. set, gives you more pieces for several jars or future batches. Think about how many jars you typically ferment and how much storage space you want to use.
Look at Cleaning and Material Details
Smooth glass is generally straightforward to rinse, but cleaning instructions vary by product. Elementi and LELELUK are described as dishwasher safe, while other listings describe the weights as washable or easy to clean without specifying dishwasher use. If lead-free material is important to you, look for that claim in the product details rather than assuming it applies to every glass weight.
Check What the Listing Does Not Specify
Not every product lists its exact diameter, weight, or dishwasher instructions. Missing details do not necessarily mean a product will not work, but they make direct comparison harder. When a particular dimension or care method matters to you, confirm it in the current product listing before buying.
