2023 New Invention Squidopop Round Fidget Double-Faced Sucker Sensory Pop It Toy Stress Relief Suction Cup Silicon Bubble Poppets for Kids and Adults

This sticks really well and actually holds my phone as pictured! It doesn’t really stick when thrown at a window, but perhaps I’m just doing something wrong. It would be nice if it was a bit larger it is pretty small and thin, but the seller did clearly list the size, so I knew it would be small. Overall a fun and functional product, whether you plan to use it to stick things to each other or as a fidget toy.
