グローポップチューブ

The glow effect in a dark room is way cooler than I expected, and the tube collapses down small enough to fit in my pocket. I keep one at my desk and twist it around during calls.

My kid has been twisting these into spirals for a solid hour and they haven't lost their shape yet. Collapsing them down to shove in a backpack is way easier than I expected.

Bought two of these for my desk and I keep bending them into knots while on calls. The collapsing part is handy since they shrink down to almost nothing in my bag.
