Vacuum seal storage bags L for travler’s clothes E001 from daiso (01-07-19)

It seems to have a japanese brand no idea what is it but its from daiso imm anyways. Daiso does change its item list so you can never be sure you will be able to find it again later. Anyway

Basically trying it out. It says it should shrink it by half. You can use vacuum to drain out the air or try squeezing it out yourself.
