3mm width Straight Panel Line Guide, colored sheet. (Each block is 3mm x 3mm) 
 
Panel Line Guide ver.2 (Straight line) Width 3mm. Sheet size: 105x175mm, easy to customize for various straight-line carvings. Unlike regular tape scales, this scale has a thin fold line that allows you to fold at a steep angle when carving lines. It is also convenient to match the length correctly. It's slightly softer than the various cutting guide tapes, and it doesn't leave any glue when peeling off. One sheet of paper is included in one product.
