The Spear & Jackson Medium Lead Builder's Pencil is the go-to marking pencil for builders, carpenters, and DIYers who need clear, smooth lines across a variety of surfaces day in, day out. The quality graphite medium lead core glides cleanly across wood, plasterboard, brick, and concrete — delivering precise, easy-to-read marks without the scratching or skipping you get from inferior leads. The break-resistant hardwood outer casing keeps the lead protected through the bumps and drops of everyday site life, so it's ready to mark when you need it and not snapped at the bottom of your tool bag. Reliable, consistent, and built to last the job. Keep a few on hand and you'll never be caught without one.
