This product is a collection of trapezoidal panel line guides in varying lengths/ widths and shapes. Combine them to make some unique designs, all the while keeping your lines tight, sharp and straight. Peel and stick is the name of the game here, just find your desired length and apply to your clean/ oil free part. You get quite a bit for your money – 11 sheets total, no duplicates. Do you prefer 135 degree angles or 112? 1mm, 1.5mm, 2mm, 2.5mm or 3mm widths? What about straight lines? Nevermind… You get them ALL! This product is designed for the scriber who has a little experience but still wants to save time in measuring lengths and angles. Not as thick as the clear Panel Line Guides 1 and 2, so more chisel control is needed.
