Vacuum pump clothes storage bag

Vacuum bag usable with standard clothes vacuum storage bags.Ideal for traveling and maximizing space in the suitcase.Used 2 O-rings I had laying around (id 32mm cs 3.5mmm).Use light oil or grease to help the main body slide on the O-rings.The TPU valva can be inserted from the top of the piston and pressed in place using a screwdriver handle.So far tested only short term, will update as time goes.
