Metal Coil Springs – Kaiko

Who didn’t love a slinky in the 80s?

These Metal Coil Springs are a nostalgic little “science-meets-sensory” tool—weighted, fidgetable, and oddly soothing, with a gentle tinkling sound as you move them through your hands.

Made for one- or two-handed use, each coil has caps at both ends for extra smoothness and safety—perfect for pockets, desks, therapy kits, or calm corners.

Why you’ll love it

• Satisfying movement: Stretch, compress, flip and “flow” it between hands.
• Gentle sensory sound: A light, soothing tinkling as it moves.
• Smooth-ended design: Capped ends for a nicer feel in-hand.  

Sizes

• Approx. 6 × 5 cm
