The Zen clipper is an easy and safe way to trim your pet’s nails. You insert the nail into a small funnel and it cuts just the tip and avoids the quick. The guillotine cutter allows you to quickly cut just the tip of the nail. Zen Clipper has a patent-pending conical blade that only allows the tip of the pet’s nail into the cutting area, it’s like putting the tip of the nail into a small funnel. You clip just the tip and avoid the quick.
