That's the thing...I just made a lucky guess and paid no attn. Then I tossed the bottle, thinking I could buy any other kind and have the same results. But I couldn't. And I had/have no idea what the original brand was. I must have had at least two bottles of the first one bc I was doing this for almost a year. My nails were sick and everyone was jealous. And this was before anyone in high school was getting acrylics or anything so I was the only one who had these superbad nails. OMG I wish I could remember the stuff I was using. I got the tip from a friend of mine modeling. She hadn't tried it...just told me she heard that glue in nail polish helps and I just stumbled upon this. But oh so many disasters afterward, experimenting w/ wrong polishes.
