The colorful stress ball brains are perfect. We needed something to add to a key chain for XH concert with beautiful mind theme. These brains are soft but durable enough for us to make holes through them to attach to the key chain. We love the results.

I opened the box, I squeezed several of the brains. They were not hard. They were not way too soft. They looked like what was in the photo. They were basically the foam representation that I expected. They will not last forever, but they will be fun for a lot of kids this Halloween.

I expected a palm size stress ball - this was more like a walnut size.

These are not very effective as stress balls, in my opinion, as they are small, but they are a good fidget. I purchased them as a visual aide, however, and my students and I LOVE them.

Pretty consistent looking, but squishiness varies. I noticed a few of them are really easy to squish, though most of them are a firmer squish.

My students loved receiving them at the beginning of the year.

Read the description to make sure the size is okay. We purchased these and the are vibrant in color, great detail but smaller than we thought.

Some of these are soft, some are rock hard. I did check the description for size…not sure if they shrink over time but most measure barely 1 inch. I would highly discourage buying these! For $0.50/piece it’s disappointing.
