The Tajima Sumitsubo BOMZ 10m is a compact Japanese chalk line designed for marking tasks that require speed, visibility, and excellent durability on the job site. Its angled housing makes the tip more visible and improves string retention during marking, especially in corners and hard-to-reach areas.
The BOMZ model incorporates several professional features: reinforced rewind spring, a highly sealed structure that limits ink leakage, a complete tool-free opening for simplified maintenance, and an automatic "Point Karuko" system that secures the tip during rewinding. Its rubber grip also improves comfort and control during intensive use.
