What are these stress balls composed of?

Feels like a very strong balloon filled with a squishy substance that reminds me of wet beach sand and it is sealed with a metal band.

Hi Meghan...it's a composite of recycled substances...if that helps...however I've gotten excellent reviews from may patients, and the price is right!Paul

I am not sure. It is like a balloon type outer only heavy duty. Has stuff inside that moves around like playdough. I bought it for my 6 year old granddaughter that has a issue with picking. It has helped but not totally.

Both. The ball is 'squishy' and the bands stretch. The bands provide a stronger resistance.

The gel! It's made out of something that stays cool. There may be a more technical answer somewhere else.

It is a hollow rubber ball with little nubs on them. I throw them inside for my dog all the time and have never left a mark on anything. They don't make a loud thud when they bounce off of the wall or floor but they aren't completely silent. I suppose if I lived in an apartment with paper thin walls I would avoid bouning them off of common walls but I wouldn't worry about bouncing them off of anything else. They make less noise than a tennis ball.

They are in between. Not the hard regular balls but not fluffy soft either. I hope that helps.

The therapy balls are solid, same material inside and out, good material to exercise with, good quality, takes good abuse when doing therapy.I don't know if they are BPA free, no info on the box.

These are a harder plastic type. I would not recommend them for that purpose and choose to go with a more traditional ping pong ball material.

No, not like a rubber ball would. They feelKind of like big ping pong balls that may dent easily.

The balls are a soft rubber, not hard like regulation balls. They're also smaller than reg balls.

The included balls are not hard plastic like a true golf ball. They are softer and flexible but of good quality.

The ball appears to be made of vinyl. Sturdy enough for young children, but isn't a rough type material. Of course, it's smaller than a regulation basketball, and fits into little hands very nicely. Making "scores" a sure thing. :)The ball also has an air valve for adding more air, if desired. The ball, as packed, arrived with a moderate amount of airand we added a wee bit more, in order to get a bit better bounce. Hope that's helpful.

The roller ball is made of hard plastic glas-like. However, it doen NOT work (so Inever put anything in it) well because the ball holder does NOT fit the bottle well even if I jammed in th ebottle. I DO NOT recommend this item. Poorly made or sized.

They are metal, with a metal stud that is secured by in tensioner inside of the ball.

It seems like Dacron, Cotton, and Rubber. I don't have any problems with them--and I wear these jocks 24/7, as the result of a botched hernia repair. I think they are better than wearing nothing.

They are made of lightweight reinforced polymer. Very strong and reliable! Hope this helps.

I believe they are rubber..or at least something that resembles rubber and acts the same. Not inflatable.

Looks to me like some kind of low density polyethylene perhaps.They're very pliable and flexible, and they don't crack. You can even fold one in half without it cracking, and then you can form it back into shape. You can write on them with a marker too.
