Nailside is pretty much top dog when it comes to the laser mani. I tried it a few months ago but I found it really difficult to keep the tape even and the nail polish just wouldn't stay where it was supposed to.
I ordered some graphic chart tape last week so I decided to give it another go. What a difference!! This stuff is great; I got it in 1/8th in and 1/16th in. The tape sticks to the nail very well and its the exact same width every time. So much easier!
