This is a set of two 20cm transparent plastic triangular rulers. The grayed-out area is marked with the city name, "◯◯ City Board of Education." Both rulers show signs of use, and the right-angled triangle ruler has stains from a ballpoint pen or marker. I washed them before listing. Please consider purchasing if you don't mind the condition. The shipping method may be Yu-Yu Mercari Bin. I have other items for sale as well. Many items can be combined for free shipping.
