@user4610578088416: Always guessing where to drill or screw because your marker can’t reach? This 20mm long-nib marker slides right through deep or narrow holes so you can mark perfectly every time. Waterproof, quick-dry ink writes on metal, wood, glass, plastic and more. 10pcs in 3 colors—throw a few in every toolbox and stop missing the mark. #tooltok #DIYtools #markerpen #handyman #woodworking
