Review on 3D Coasters 🌌 inspired by Rick and Morty by Doug Virden

Looks Great! They have a plastic/3D look and my son loved them. However, after a few weeks of use, the 2 coasters we use split into 2 pieces (top and bottom). They're cardboard inside and the liquids he sucked up made them fall apart. I assume coasters need to be waterproof since their whole existence is to put cups/glasses with liquids on them. In the summer we drink cold drinks with ice inside, this causes condensation (small water droplets on the outside of the cups/glasses) to seep into the coaster. Maybe I have the wrong idea about the life of a roller coaster - the range and usage should be. Wouldn't recommend it.
