1" Round Mylar

The rounds were all precisely the same size, which was exactly what I needed. Other retailers had some variants in the diameter of the "same" size rounds, which meant that crimping didn't always work, but ABM's mylar rounds crimped perfectly nearly every time. They are sturdy and slightly thicker, too. Will definitely be buying from ABM again.

fantastic quality.

Love it

It is just what I need. I like that it comes with a lot.

The mylars are good quality and hold up pretty well. Easy to keep//get specks of dirt off

The product is great, and fit into my machine. I was very pleased with that :) It is an essential separate product.

Fits in the machine and works.

Like many of the others, I find I use the shells and mylar faster than the backs, so it is great being able to buy them separately.

The mylar covers always disappear faster than the rest of our button making supplies. It is super convenient and cost effective to be able to purchase these separately!
