Zhanmai 6 Pieces Brain Stress Balls Halloween Funny Toy Red Brain Shaped Ball for Teens Adults Improving Grip Strength Decompression and Relaxation, 2.4 Inch

These are perfect for a couple of days of fun, they do pick up dirt easily. My friends and I used them to throw at each other for a laugh to relieve stress.

Got it for the grandkids, they loved it, went home and exclaimed "Mom, I got a brain" . It was too funny. This was better than the big box store one, that broke too easily. Would be a great practical joke gift. For someone who has claimed they lost their mind. It feels a bit sticky.

These are great little brains they look so real I actually broke one of my porcelain dolls heads and I used one to put inside of it to keep it on display in our Oddity shop worked out really well they're fun

It had an odor, was sticky, plug interfered with squeezing, and I trashed order as had already opened and tried two of the street reliever toys. I have ordered similar items on last three holidays and have loved them. I order from same seller company and will seek them out again before Halloween.

Fine for my purposes (brain jars), but these have a very strong, weirdly sweet, generally chemical smell.

These were great for my high school psych students! They also made great stress balls to squeeze during exam season. Planning to purchase them again.

These are great gifts and stress relievers!

These are fine. I decided not to use them, however.
