Arthur Europe Diamond is a grippy non-tacky offensive rubber manufactured in Germany. It offers a more elastic and immediately responsive feel than the tacky Rxton line, with strong speed, direct blocking and counterlooping potential.

Official LOKI data: sponge name, printed hardness, currently selectable thicknesses, colours and hardness codes, taken from current LOKI product information.

LOKI's printed degrees are manufacturer values on LOKI's own scale. A LOKI 37° is not assumed to be equivalent to an ESN 37°. The TTDNA hardness rating is a separate editorial normalisation.

Competition approval is only shown once it has been checked against the current ITTF list of authorised racket coverings. A shop listing on its own is not treated as proof, an approval is never inherited from another model in the same family, and an unverified covering is never shown as illegal.

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

Variants and configurations

1 variant

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.

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