Our tear-proof keyfobs are exceptionally durable with a biodegradable core, due to our exclusive manufacturing process and they can be cut to any size or shape. We use a unique synthetic polyester substrate that, when heated during production, forms a permanent bond with the encapsulate, giving it added strength and flexibility. The finished product is a highly durable waterproof keyfob that can be custom-designed, printed, sealed and cut to your requirements.
