Haifu · Haifu Marine · Medium pips

Penguin

Penguin sits between short and long pips. The taller pips bend more on contact, which produces a less predictable trajectory and partial spin return, yet the sheet is still direct enough to punch and hit with. It is stored as medium pips and is never merged with Dolphin or Octopus.

Approval evidence and market availability are recorded separately. A commercial listing is not proof of current ITTF legality, and an approval listing is not proof of current production. Approval is never inherited by an edition, and no expiry date is invented.

Market status describes current commercial availability only. A sold-out button or a low-stock warning is a stock state, not a discontinuation, and where availability could not be verified it stays unknown.

Haifu states sponge hardness on its own degree scale. Those values are preserved verbatim and are never converted to an ESN degree.

No reliable official Haifu list price is published per region, so no price is shown rather than an invented one.

TTDNA values are TTDNA's own editorial 0–100 ratings. They are not official Haifu measurements and are never a conversion of the Haifu manufacturer scale.

Short pips, medium pips and long pips behave differently: short pips hit flat and generate some spin of their own, medium pips add wobble and partial return, and long pips mainly return the incoming spin. Generated spin and spin reversal are separate ratings.

Haifu also sells glues and boosters such as Sea Moon and the Blue Whale glue and booster products. Those are not rubbers, so they are excluded from this catalogue rather than mixed into rubber filters or comparisons.

Commercial, provincial, national and training editions are structured properties of one canonical product, never separate records. Factory tuning is stored per edition and is never inferred from an edition name, and an edition never inherits the commercial version's approval.

Factory tuning status is a separate fact from the edition level. Where no source states whether a sheet leaves the factory tuned, the status stays unknown rather than being assumed.

Strengths

  • Variation and wobble
  • Still usable for active hitting

Weaknesses

  • Less reversal than true long pips

Best for

  • Backhand variation players

Not ideal for

  • Players expecting full long-pips reversal

Generations are never merged automatically. Blue Whale I, II and III, White Shark I, II and III, and Pirates 07 and 08 are separate records, and no specification is copied between them.

Variants and configurations

3 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.

Known users

All-round players who want pips that mix blocking and hitting with some spin of their own.

Haifu publishes no athlete roster for this sheet, so TTDNA shows the player profile it is built for instead of invented names.

Family membership groups related names. It never means shared construction, and family members are never merged into one record.
