Product Safety Information
Our Sensory Worry Stones are designed to provide tactile sensory stimulation and fidget support.
Please follow the recommended age guidance provided on each product page and supervise young children during use where appropriate.

✔ CALMING, FOCUSING & TACTILE
Give busy hands a satisfying sensory experience while the child gets on with their day. The soft silicone stones can be rubbed, pressed, squeezed and explored, providing different tactile sensations that may help reduce stress, refresh the mind, and support a child's focus and concentration. They can also offer a simple form of fingertip massage and may provide anxiety relief through soothing, repetitive touch.
✔ ENGAGING, FUN & COLOURFUL
Designed to make sensory play exciting, Kalmzo brings together six colourful silicone stones, each with its own tactile texture to discover. From smooth surfaces to ridges, bumps, waves and dots, every stone offers a different sensation for curious little fingers. A simple, hands-on activity that keeps children engaged while they explore, touch, and play without a screen.
✔ SOFT, SILENT & EASY TO CARE FOR
Made from soft, flexible silicone, Kalmzo stones are comfortable for little hands to hold, squeeze and explore. They're completely silent for quiet sensory play, while their washable design makes them easy to clean and reuse. With six vibrant colours and varied textures in one set, children get plenty of sensory variety without needing screens, batteries, or noisy moving parts.
✔ A BETTER WAY TO KEEP BUSY HANDS ENGAGED
From nail biting and restless hands to endless screen time and difficulty settling into homework, children often look for something to do with their hands. Kalmzo offers a simple, screen-free alternative with six colourful silicone stones and different tactile textures to squeeze, rub, and explore. The satisfying touch can help redirect restless habits, support focus and concentration, reduce stress, and provide a calming sensory activity when children feel bored, overwhelmed, or distracted.
✔ PLAY, EXPLORE & CREATE
There’s more than one way to enjoy Kalmzo. Children can squeeze, stack, arrange, mix and match, or explore each texture with their fingertips, turning the stones into an open-ended sensory activity. The bright colours and varied silicone surfaces encourage children to experiment and create their own ways to play, making every session a little different.
✔ MADE FOR EVERYDAY MOMENTS
Kalmzo fits naturally into the moments when children need something to keep their hands engaged. Use a textured stone during homework to help support focus and concentration, or take one along for car journeys, holidays, and days out for a quiet, screen-free activity. With six bright colours, six different textures, and soft silicone surfaces to squeeze, rub and explore, Kalmzo gives children a satisfying sensory experience wherever the day takes them.
Why Kalmzo Is Different
Not all fidget toys are designed the same. Kalmzo combines six unique textures in one quiet, screen-free sensory tool—giving hands more ways to squeeze, rub, roll, and explore.
