Hear hear!! It's not like CND are in the habit of ever producing more colours that are the same or similar just for the sake of it .... But it seems according to others, that some other companies do just that and I have read quite a few complaints about it here on SG. Perhaps they do it to say how many colours they have opposed to Shellac? Lol. I think we all know that it is much easier , simpler and more cost effective to have quality of choice rather than quantity of choice.
I have a friend who uses another brand and she told me she had bought every single colour of over 100 colours. Apart from gathering dust on the shelves, some have also quietly been curing rock hard in the bottles on the shelves and she has wasted many many pounds and now has a load of 'gone off' stock. The bottles were not in the sun but neither hidden away in the dark either. Just in the salon. I had the same thing happen to me with the same brand and I had kept them in a dark cupboard; 1 year later and when I opened each of the three, the brush was stuck into the cured gel and it was all unusable. I personally don't own even all of the Shellac colours!! Bet that's surprised you!!
