ガンプ メモリーゲル ストレスボール クールカラー 3個セット

Squeezed one of these during a long phone call and the gel center gives way nicer resistance than the foam balls I've tried. It springs right back to shape too, so no weird dents after a week of fidgeting.

I keep one of these on my desk during calls and the squish is weirdly calming. The gel center means it never gets crunchy or loses shape, and there's zero slime mess on my keyboard.

The gel center makes these way more satisfying than the foam balls I've tried, it squishes deep and then bounces right back into shape. I keep one in my bag for waiting rooms and it hasn't leaked or gotten sticky after a few weeks of daily squeezing.
