Now in BioMed resin: the same design and the same glow, printed in a durable, medical-grade clear resin. The original Dental resin is no longer available for manufacturing. The original Wolfcat profile, in clear resin. A few of our oldest devotees will remember this shape; it was later refined into the Wolfcat we print in nylon. Wolfcat Crystal Claws run longer than Kitten Crystal with slightly rounder tips, built for slow, sustained play. BioMed is biocompatible and engineered for impact and abrasion resistance, so the points hold up to knocks and everyday wear. The material is certified to USP Class VI, has passed ISO 10993 testing for skin irritation, sensitisation and cytotoxicity, and is rated for long-term skin contact and short-term tissue contact. Body safe when used responsibly. In daylight they read as clear ice. Under UV they light up, and the glow is the resin itself, so it never fades. Everyday cleaning: warm soapy water after every session, never hot. For a clinical standard of clean, wipe down with Viraclean or a similar hospital-grade disinfectant, or 70 percent isopropyl alcohol; each set can be sterilised for hygienic reuse. A few sets in our original Dental resin remain in some sizes at a clearance price while stock lasts. The two resins are almost identical in appearance.
