This is the same type of glue that Veterinarians use for sutures. Works great for strengthening artificial and natural nails with less brittleness than regular nail glue. n-Butyl cyanoacrylate glue is different from regular types of fingernail glue, (ethyl cyanoacrylate). It's less brittle, and has very little odor.Our n-Butyl glue works great for applying our pre-formed nails. It also works great when used with silk or fiberglass wrap. Creates a very smooth, durable nail.We also include dispensing pipettes and silk wrap with each order.An equivalent to our n-Butyl glue is "Vetbond tissue adhesive". They sell 0.1 oz (3 ml) for over $25.00. We have 3/4 oz bottles, over 7 times as much, (22 ml) for $13.95.We recommend using regular nail glue or super glue for applying our Instant Nail strips.
