Yelli – The Cheerful One
A mood booster for gray days, a little glitter break when tears fall — the Calmi Cube "Yelli – the Cheerful One" brings color and lightness to any tension. Developed with occupational therapist Silvia Resei (@ergotipps), it's ideal for children aged 3 and up and adults alike — with a carabiner clip.
The magic happens with the first stroke: reversible sequins change color under your finger and can be turned back again, a magnetic butterfly gently folds open and closed, an hourglass lets tiny beads trickle silently downwards, a lacing cord finds its way through the loop. By stroking, folding, and observing, eyes and hands find a rhythm that transforms a bad mood into curiosity — targeted sensory input instead of overthinking. In everyday life, Yelli becomes a colorful mood helper: quietly stroking the sequins on the couch after a difficult day at daycare to soothe the feeling of tears, opening the magnetic butterfly during a tantrum in the car and learning to breathe slowly, watching the hourglass trickle in the waiting room and calming down.
Lovingly crafted from OEKO-TEX® certified materials — cheerful and colorful, so it lifts the spirits just by looking at it. A fidget tool that helps children and adults through difficult moments — the perfect gift for anyone who needs a little more color in their daily life.
