This is the same type cyanoacrylate glue that Dr's and veterinarians use for sutures. It's very different from any other type of nail glue. It's strong, but less brittle, and makes a great fingernail glue. Very thin, wicks very well, and has no irritating odors. The equivalent to this glue is "Vetbond tissue adhesive". They sell 0.1 oz of that for about $20.00. We have 1/2 oz bottles (5 times as much) for $9.95.
Please see our "Helpful tips" page under n-Butylcyanoacrylate for more info.
