BIG OX is a blubbery, thick cockring made from our exclusive PLUS+silicone, which combines the strength and stretch of TPR with the warmth and softness of smooth silicone. BIG OX is designed to grip your meat with smooth snugness and give you even more girth. The soft, fleshy material and squishy design are built for comfortable wear and use. If you're into ballstretching, BIG OX also doubles as a hefty stackable ballring for some stretch on your sack. 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
