About this category

School and art supplies sell in a strong seasonal rhythm, and parents, students and artists look for products that solve a specific problem. This collection includes a backpack insert that unfolds into a hanging desk organizer and a sharpener that leaves a long exposed lead for sketching, a pencil cap with a tiny camera that measures the point and reminds you to sharpen, and a hard folder whose spring-mounted hinge and catch clamp any thickness of paper.

The patents were filed only in China, so they do not restrict these designs in the US. Our product pages explain each design, where it is useful, and the US rules that matter - children’s products for ages 12 and under need third-party testing and a Children’s Product Certificate.

What to look for in this category: products that photograph well for back-to-school campaigns and can be bundled with existing ranges.
