ARK SensaStones™ are discreet, worry stone-inspired keychains designed to support self-regulation, focus, and calm throughout the day. Easy to keep within reach on keys, bags, or in a pocket, they offer a quiet, grounding sensory experience whenever it’s needed - without drawing attention.
Each SensaStone features a distinct texture, allowing you to choose the level of tactile input that feels most supportive:
-
Smooth (Blue, Pink) - Similar to a traditional worry stone, with a satisfyingly smooth surface for gentle, calming input
-
Lined (Yellow, Purple) - Raised lines provide mild tactile feedback for steady, rhythmic fidgeting
-
Bumpy (Red, Teal) - Raised bumps offer the highest level of tactile input for those who benefit from stronger sensory feedback
Together, the range provides graduated sensory experiences, making SensaStones a versatile option for teens and adults seeking a subtle, portable fidget for stress, anxiety, focus, or emotional regulation.
