About the Handling of Unshu Soroban (Birch Beads):
This indicates it is a traditional craft from Okutama Town, Shimane Prefecture.
Properties of Birch Beads:
Because it is a dense and hard wood, the beads will become more familiar to your fingers and gain luster with continued use. Unlike plastic beads, they are less prone to static electricity, which prevents miscalculations caused by beads moving unintentionally.
Storage Precautions:
This is a wooden product and is very delicate. Please avoid storing it in direct sunlight, in places with direct air conditioner drafts, or in humid locations. Store it in the included case.
