Honestly I feel like others should know too just in case: squishamals have a ball of memory foam inside of them, and honestly it may be a little uncomfortable to squeeze if you have joint problems because it takes a little force. I tried all that were in the Claire's i got it from, trying to pick the softest one, and I chose this one and it's still honestly a little straining. They're harder than slow rising squishies and squishmallows, but softer than normal common foam stress balls. I hope that helps you AND others! :)
(Maybe some can be softer than mine and I just havent found one? Maybe they're are some that are softer, I'm unsure, but this is my experience!)
