Oyasaicrayon mizuire inc. A safe set of 10 crayons made from rice bran oil and vegetable-derived ingredients. Purchased when my child was 1 year old. All colors were used a little, but they are still in usable condition, so I am selling them. * Immediate purchase OK * Please ask any questions before purchasing. * Even if you are negotiating a price or asking questions, the person who presses the purchase button first will be given priority.
