Question: Are these bpa free?
Document: love these. love they are reusable. love that they are bpa free. love that they are easy to use. would def recommend.
the old school 2 part lids definitely work great, but these plastic lids are more practical top for todays saavy kitchen chef. bpa free.
I love mason jars and use them for almost everything. Unfortunately....particularly in the kitchen...the canning jar lids have bpa. In steps these storage jar caps. Not only are they so much easier to use because it is only one piece instead of two, but they are bpa free! Also, they have been great fro transporting my lunches, i pack salads and yogurts in mason jars to bring to work. No issues with leaking. Love these.
These BPA free canning lids do not rust like the metal but keep a tight fit for fermenting just the same.
Pros: no worry about rust; last longer than the aluminium cap.Cons: not BPA free and not leakproof
These BPA free lids are very convenient and handy. It makes jars spill proof and bug proof. I like them a lot!
No more rust and BPA free....! My lidless jars are useable again ...Price and product are a win win .. Service prompt and item exceeds my expectations ....
Perfect canning jar lids, wish I knew about them before! Very happy they are BPA free too, as I keep homemade baby food in the fridge with them.
terrific replacement caps for canning jars that dont rust and are BPA-free. Fits regular mouth jars perfectly. I highly recommend
Glad I got these for almost free because they are absolute junk. They are only good for sitting in the fridge to hold something that won't move, otherwise they will leak and spill everywhere!
Answer: Yes, they are BPA FREE! It is stated on the from of the box!!
