This is my second set of whitening pens. I got the set last year and it worked kind of okay, but the pens dried up and I couldn’t revive them. Looking to reorder, imagine my surprise when I saw a demo telling you to twist the other end to release the whitening fluid! That little detail isn’t in their included instructions anywhere! I had been using it with no gel and just the blue light for weeks! I have high hopes for better results this time, but Cheeky, maybe rework your instructions.
