We are pleased to introduce a unique set of fluorescent crayons, brought to us by Kokuyo of Japan. This 10-piece set creates beautiful, transparent colors, allowing for innovative sketching techniques, such as overlaying colors on line drawings. Additionally, these oil-based crayons glow in the dark when exposed to UV light, adding a fun and exciting element to artwork. With their soft and smooth application, these crayons are a wonderful addition to your child's art supply collection.
