The craft

Made by hand, shaped by the islands

The majority of the materials we use comes from the Marianas or the Pacific. We gather with intention, taking only what the land and sea offer freely.

Every piece passes through carving, sanding, and polishing — each stage done by hand. No two pieces are identical.

Island heritage

Rooted in the Marianas

Saipan's beaches, flame trees, latte stones, and ocean waves are not just backdrop — they are the source. Every material we gather, every form we carve, carries the memory of this place.
