Fly check in bag in PVC free plastic. The check in bag is re-sealable with nylon zipper, which is a grip “friendly” design, behind the zipper pendant that makes it easier to open and close. The check-in bag meets the requirements IATA has set by default. The rules of use are also found inside the check in bag. It’s also great as a cosmetic purse. Gillian Jones Check Inbag Transparent
