بلوك بامبي

I got these for my kid who chews through every shirt collar, and the block shape makes it easy for him to grip while the different sides keep him busy. Tossed it in the dishwasher after a week of use and it came out fine.

The four different textures on this thing genuinely saved my hoodie sleeves — I keep one in my pocket at work and switch sides when one gets boring. Tossed it in the dishwasher over the weekend and it came out looking brand new.

I chewed on the smooth side for a few minutes and then flipped it to the bumpy one when I needed more input, and that variety really keeps my jaw busy. The rectangle shape fits nicely between my molars without being too bulky, and it's held up well so far.
