This is a drool cover for a baby carrier. I purchased it from a Rakuten shop about 3 years ago. It's made of 6-layer gauze and is reversible. I washed and stored it with detergent only. The cover on the top in the first photo has some yellowing. It can be easily removed with snap buttons. Babies put the shoulder straps of the baby carrier in their mouths, so this is used to keep the carrier clean in place of the carrier itself, which can't be washed frequently. I'm decluttering, so I will offer a discount to those who purchase multiple items together.
