Our GuitarPlayerNails Fingernail Protector is the strongest and most durable nail strengthener and protector available. It will give you incredibly strong natural fingernails that sound great. Unlike ordinary cyanoacrylate fingernail glues (super glues), this product adds very little brittleness to your natural nail, and has no irritating odors. We include 6" of silk wrap with order.
