Bon Tool Tajima Chalk Box with 1mm Thick Line (84-887) - Perfect for Construction, Masonry & DIY Projects

What can I really say about a product that does everything it’s supposed to? Strong, crisp poly line doesn’t tangle or break. The body is cast (aluminum?)- light, but strong enough to survive a few trips off the roof. I’ve never had the winding mechanism fail me. The only reason I’ve ever replaced one is because I lost it. I would highly recommend this product.
