Review on 🥤 Convenient Plastic Reusable Concealable Drinking Cup by Joseph Stone

Yes, you read the title correctly. I am a professional diver and my colleague passed away earlier this year. I brought this to her memorial service at Neptune Memorial Reef for a toast. The dive takes place at a depth of approximately 45 feet off the coast of Miami. I needed something that would seal and not be affected by the pressure drop as the volume is removed at depth. They worked great. There were no leaks or breaks, and it's easy to swallow and go deep. You just have to hold it upside down and hold your thumb on the end. **Tip: If using them for an underwater event, use tequila as it pairs well with salt. Don't be an idiot either, because you can die if you become stupid.
