Purchased about a year and a half ago and used 3-4 times for resin crafting. It has been stored in its box since then. There are some scratches or stains on the inner tray. I personally don't think they are very noticeable. Each use was for a short period of time. The instruction manual is also included. The box is slightly torn. If you don't mind, please consider purchasing. For those who are thinking of starting resin crafting, how about it? UV light Resin Gel nail Curing
