North American Rescue Hyfin Vent Chest Seal, Original Version 2 Count (Pack of 1)

As expected

One of the geodes was solid one was hollow. The solid geodes are nearly impossible to break open as they are a rock. The whole point of purchasing these is to have hollow geodes that your children can break open and inspect crystal formations inside. If the entire geode is full of minerals then there is no crystal formation to inspect. You can tell from the weight of a geode if it is hollow or not. They do not care enough about product quality to only send hollow geodes that your kids will enjoy.

Good price

Good

Good quality

Only received one of the seals. Apparently someone ripped off the bottom package. Dissatisfied and disappointed because this is a life saving device. I have order these before and always got two separate packages attached together. Will be returning.

Great for injuries
