Our new Kaiko Hand Spring can be used one-handed or with both to squeeze and manipulate the coils. It is great for high resistance, discreet fidgeting & keeping hands busy. Can also be used for hand function and strengthening. This tool provides strong resistance. It is most suitable for teens and adults. Not suitable for little hands & is not a toy. Please take care when stretching the spring so not to get the skin caught in between the coils. "I bought a bunch of stuff for the kids at school, but this one I bought for me, and I LOVE it! I love the feel of the coils and the coldness of the metal in my hand. I also love the level of resistance it provides and it's the perfect size for an adult hand. I was impressed with the quality of this one too. A great find and a great fidget! Lisa D jan 2025" Approx. 10 cm unstretched in length & 5.5 cms across. Made from Zinc, Steel & ABS plastic.

The resistance on this spring is just right for building up hand strength during long meetings. I love that I can use it one-handed under the desk without anyone noticing.
Abigail★★★★★
I keep one in my work bag and another at my desk, and the coil spring action is perfect for silent fidgeting during meetings. It takes a surprising amount of force to squeeze, which makes it feel more like a stress reliever than a toy.
Nicholas G.★★★★★
The tension on these coils is just right—firm enough to give my fingers a real workout without being impossible to squeeze. I keep it clipped to my bag for meetings and it’s been a lifesaver for focusing during long calls.
