HMS is changing how denim gets its worn-in look.
HMS, short for Hand Made Stone, began as a patented reusable alternative to pumice stones for denim and garment washing.
It keeps the authentic abrasion denim needs, while reducing the waste, sludge, dust, water use, transport weight, and process issues created by pumice.
Today, HMS includes industrial stonewashing media, dry-process tools, and hands-on workshops that connect cleaner production with denim culture.
Cleaner impact, built into the process.

Disclaimer:
Savings and reductions depend on recipe, machine type, production volume, utility costs, waste treatment costs, and local process conditions. Site-specific trials are recommended.
Pumice breaks down. HMS holds up.
Traditional pumice creates sludge, dust, extra handling, storage pressure, and hidden costs.
HMS is designed to create authentic abrasion with far less waste and more control.
