Got these a few years ago and if I remember correctly I got the regular set then got the skin tone set and also the pastel set that''s on Amazon. When I got them I used them for a week or 2 then kinda stopped and over the last few years I''ve used them a few times here and there and I mean maybe 1 time every few months. I did swatches as I counted the markers to make sure they all still worked some of the brushes seemed kinda beat up on a few idk if it''s from sitting but I did switch them around. Most markers seem like they still have plenty of life but keep in mind they were mildly used and have been sitting so some markers may be close to drying up or some may have never been used. Thanks
