In a chamber machine, Read some reviews tonight from a guy that instead of using bags (and their associated cost) for items that he’d get into frequently, he instead would use canning jars with canning lids. Guy said instead of damaging the seal on the canning lid, he pokes a hole in the lid with a thumb tack. Then covers that hole with electrical tape. Then reuses the lid in the chamber machine. Said the tape makes a seal and can get 10 or 12 reseals with one piece of tape.
