I've definitely something better awaits. Use for 1 1/2 years, Shellac, Allerding not the original of CND, but the extremely satisfied by the company Bluesky and I am. Have the Shellac hitherto always deducted, although was always quite a tedious affair, then I searched the net for an alternative and came to the tip with pure acetone. This method was then only laborious, then I thought, well, wenns the cheap acetone does not bring variant, then maybe the original expensive product. Unfortunately, that's just as bad as pure acetone, but with a better smell.
