I believe this is a set that can be used for nail care or resin crafts. ●The UV lamp appears to have been used a few times after being opened. I took it out of the box and took pictures, so please check them. It's a relatively simple design. The box shows signs of age. ●Please note that two of the molds in the bottom left show signs of use. Due to the nature of the material, all four types may have dust or glitter attached, but please forgive this. Please also check the images. I am looking for someone who will purchase everything together, not in separate lots.
