This is a great BPA-free plastic topper that turns a canning jar into a drinking vessel. We use it around the house to drink out of a mason jar with a stainless steel straw, and we also insert it on top of the regular silver lid, but under the ring, to keep the jar sealed, when in transit. When we arrive at our destination and get thirsty, out pops the silver lid, on goes the Mason Bar and ring, and then we're ready to get hydrated.
People have also been buying Mason Bars and our paper straws for festive sipping at BBQs, garden gatherings and birthday parties or showers.
Dishwasher safe, made in the USA.
NOTE: This listing is for the topper only. The topper does not come with a straw. Please see our selection of stainless steel straws that work well with the Mason Bar!
