Yinhe lists hardness either as a Chinese sponge degree or as a named grade. Both are shown exactly as published and are never relabelled Shore A, Shore C or ESN. No reliable official Yinhe list price is published per region, so no price is shown rather than an invented one.

Variants and configurations

4 variants

Colour, thickness and configuration are variants of one model — never separate products. Colour never changes a rating, MAX and OX stay qualitative labels, and OX carries no sponge hardness.
