My Granddaughter is in love with this fidget set. The dimple fidget is stronger than other dimple fidgets we’ve bought in the past. It makes a slight popping sound each time you pop it. It came with a connection to put this on her backpack or purse or even a key ring. It’s colorful and fun. The squishie is the type that feels like it is filled with a type of sand and is more firm. It makes a squishie sound when pressed due to the sand particles rubbing against each other. Very calming.
