Wow 4 weeks!!! im so impressed!! i can barely get 2 weeks out of mine its usually only 7 or so days
A couple had peeled of with her help but apart from that they held up remarkably well.
Strange thing is my recent mani has also held up well (IBD Indian Sari with gelcolor base and top coats). I think gelcolor has played really well with the opi gelcolor, it didn't last well with Shellac for me.
