袋子封口器 / Sealer


After we eat snacks, there are always some left. Then, we use a clip clip the opening of bag to prevent damping. But in this way, wet air can still enter the bag
because there may still have
holes. The sealer we designed can solve this problem. First,gather the opening and through the ring. Second, turn over the
bag from inside to outside. Then seal the mouth with the cork. It will be really effective.
