The CutterPillar Glow Ultra is the largest, brightest light-board in the industry. Measuring 26" x 19" (24" x 17" illuminated), this lightboard and cutting mat is ideal for those who need extra room for scrapbooking, quilting, card‐making, tracing, embossing, jewelry-making, and sketching. The flicker-free 4000lux LED lights never get hot to the touch and last up to 50,000 hours. They provide no shadow or glare, giving you the most comfortable lighting environment possible. It comes with a one-of-a-kind translucent, non-slip, self-healing cutting mat that allows for extended cutting with most cutting tools, i.e., rotary cutters and craft blades. The mat even has easy-to-see grid lines, multiple rulers, and angles, covering the board from edge to edge. Cutterpillar's Glow Ultra is plug-in only, but it does come with a USB cord and wall plug. You can also use it with most USB power sources like a sewing machine or computer.
