Review on 🌾 Warm and Natural Cotton Batting Review: 72x90 Twin Size by Warm Company Batting 2391 by Lauren Perry

It says cotton; However, you have to do a thorough investigation to see that it is pierced with polymer fibers, making it 87.5% cotton and 12.5% polymer fiber. I was looking for 100% cotton batting. I did several microwaves with it before finding out (after much research) that it is NOT safe to use in the microwave. It's also a much thinner batting than others I've bought. I wouldn't buy it again. It was a waste of my money.
