The Tajima Sumitsubo Light is an ultra-compact Japanese chalk line designed for small marking tasks and hard-to-reach spaces. Its mini size makes it particularly practical for quick jobs, finishing work, and tight areas where a classic chalk line becomes cumbersome.

Despite its small size, this model features several professional functionalities: a chalk line return slowing system, a fine "barber clipper" type nozzle for easy marking in corners, anti-leak seals, and absorbent cotton allowing for even ink diffusion. Its simple and reliable manual system makes it an excellent compact tool for carpentry, framing, and DIY.
