This is a strawberry-flavored tooth-wiping sheet. It's very convenient for brushing your teeth when you're out and about! I'm selling these because my child didn't seem to like the strawberry flavor. There's no expiration date listed, but I bought them at the beginning of last year. I will flatten the box and include it. There are 42 packets, but I used 4, so I will send 38 packets. #Pigeon #PIGEON #Baby #Toothbrushing #ToothbrushingSheet
