This is the same type cyanoacrylate glue that Dr's and veterinarians use for sutures. An 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, over 14 grams) for $11.95.
n-Butyl cyanoacrylate glue is different from standard types of fingernail glue, (ethyl cyanoacrylate). It's less brittle, and has no irritating odors. It's great for those who want a milder nail glue. It's very thin, wicks very well, and when used correctly, it makes a great, durable fingernail glue. Our n-Butyl glue works great for applying all of our pre-formed nails. We recommend our regular fingernail glue, or ibd brush-on nail resin for use with our Instant Nail strips. It's important to wipe the top of the bottle thoroughly after use, and to store this glue upright in a small glass or cup. If you want to travel with it, you can put some into a pipette, and store it in a small plastic bag.
We also include dispensing pipettes and fiberglass wrap with each order.
