There's nothing worse than capping your Mason jar with your leftovers with a regular lid, tossing it into your lunch bag, having it tip over, and leak over all everything! Well lunch time disasters are a thing of the past with our leak proof silicone sealing rings.

I 3D print custom mason jar lids and these rings are what I use to make the lids actually seal shut. They work perfectly every time!
They are perfect, exactly what I needed for my mason jar lids
Love their products!! Great service and fast shipping. They have so many items, it is amazing!!
Work very well - especially when using with plastic caps because of high vinegar content. Will purchase again!!
Satisfied with the purchase from this store. I bought silicone seals for jars, and I have to say, they are of excellent quality. Additionally, the price is much better than that of sellers on Amazon. It's nice to deal with people who care about their business. Best of luck to you!
