Do-A-Dot 彩虹標記筆教室套裝

These markers are great for keeping the mess contained—the sponge tips don't drip at all. My only small gripe is that a couple of colors ran out pretty quickly, but the washability makes cleanup a breeze.

The sponge tips are definitely gentle for tiny hands, and the washable claim held up when we tested them on skin. I just wish the ink didn't bleed through thinner paper so fast, but for a no-mess classroom option it's decent.
