830 is stored as an independent canonical product. Approval evidence is recorded under the exact printed name and says nothing about whether the rubber is currently manufactured.
Also listed as: Double Fish 830 · DoubleFish 830
Specifications and evidence
Approval evidence and market availability are recorded separately. A name listed by an approval source is not proof that the rubber is currently on sale, and a rubber on sale is not proof of a current approval. Approval is never inherited by a suffix or edition, and no expiry date is invented.
Market status describes current commercial availability only. Where it could not be verified it stays unknown rather than being guessed from a shop listing.
Printed hardness values are manufacturer figures on the maker's own scale. A printed Chinese degree is not assumed to equal an ESN degree, and no hardness is inferred from a product code or a sponge colour.
No reliable official Double Fish list price is published per region, so no price is shown rather than an invented one.

Variants and configurations
1 variantColour, 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.

Known users
Offensive club and league players who want a spin-first inverted sheet on the forehand or backhand.
