CONNECT is a c-ring with an attached ball-ring–the shaft is super rubbery and can be worn for long play and the ball-ring is the right size to tug without digging into you. The 2 rings are attached with a wide connector that acts like a rubbery flexing spring, it’s strong enough for plenty of pull, but stretchy enough for a lot of tug. Hnkyjunk makes toys that work–there are many c-ring/ball-ring combos but none connect the way ours does with rings designed to fit and feel right with a really good tug! Hnkyjunk PLUS+silicone TPR/silicone blend: silicone for a smooth and warm feel, TPR for amazing stretch and strength. Phthalate free. LUBE SAFE: Water-based lube, hybrid or silicone lube, oil-base lubes not recommended. CARE: Wash after use in warm soapy water, air dry. Store toys separately :we recommend storing in breathable cloth pouches or for larger toys, in cotton socks.
