Both have been used only a little. The oil pastels have holders, so you can join them when they get short. You can use them until the very end. The watercolor crayons can be dissolved in water and used with a brush. You can also shave off a little of the colors you want to mix, dissolve them in water, and create new colors. The bonus green case contains clips and magnets. It's useful for keeping your drawings together. I'm also selling other writing instruments. Please take a look if you'd like. I also accept combined shipping. ★Used items, or even new items that have been stored for a long time, may have some minor stains.
