Booster JP
A tension short-pips rubber designed for active close-table attacking, blocking and direct hitting. It offers strong attackability with more spin potential than a purely disruptive short-pips construction.

Mizuno publishes a sponge degree without naming a laboratory standard, so it is shown as a Mizuno sponge degree and never relabelled Shore A, Shore C, ESN or Chinese hardness. Stock availability is not tracked in this snapshot. A sold-out product is never treated as discontinued.

Variants and configurations
6 variantsColour, 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.

Fast-block and hitting players — pen-hold forehands and close-to-table backhands that punish topspin early.
Mizuno publishes no athlete roster for this sheet, so TTDNA shows the player profile it is built for instead of invented names.
