I took a chance. they are cheap. shipping costs as much as the product. they dont fit my coffee mug. I have to wait until replacement lids are in stock. No idea why I have to buy a new lid when all it needs is the seal ring.
The delivery was unexpectedly fast, and the rings fit perfectly. Very happy with the product and the service.
I needed a replacement o-ring for the cover on my 32oz bottle which has been discontinued. The o-rings are not the same size as my original o-ring but they do the job.
Order returned because our local usps is horrible.
I ordered a pack of six silicone rings. They were shipped super fast. These new rings have a groove along the edge that the original didn’t, but doesn’t really affect the seal like I thought it would. Depending on how old your cap is these rings may not fit snug.
