All yo-yos have passed the manufacturer's quality inspection. Quality standards vary by manufacturer. Basically, products that can be used normally are within product specifications.

Examples of possible initial defects

  • if the following symptoms occur immediately after opening, they may be initial defects:
  • (Bind models only) The bearing barely rotates even when flicked with a finger.
  • Even after dampening vibrations with a finger during play, the yo-yo vibrates so much that its shape appears distorted.
  • Parts that should be installed (bearings, pads) are not installed.
  • Examples that do not constitute initial defects
  • Package damage
  • Color differences from expectations
  • Bearing noise or bind model return issues that occur after even a few plays
  • Yo-yos that arrived properly assembled but cannot be reassembled after disassembly
  • Scratches on the inside of the bearing area, paint chips
  • Color variations on the yo-yo that are not noticeable from a distance
  • Paint chips that are not noticeable from a distance
  • Scratches on the yo-yo that are not noticeable from a distance and barely detectable by touch
  • Minor rust on bearing surfaces of models that come pre-strung in the package (minor external rust has almost no impact on performance)

Description

yoyorecreation - E=mc2

It is a B-Grade E=mc2 (Raw). It does not have a package.

"E=mc2" is Hiro Irifune’s (AKA Roan) signature model of the new Stardust variations “Tatsuya vs. Roan.”

Due to the product design, it has a very high chance of having some vibes. Specially after you unscrew or hit them on the ground. Please understand the nature before you order.

Having played with YYR’s original Stardust since its first prototype, Irifune has earned his first signature model, the “E=mc2,” also known as his "Relativity Theory." Irifune upgraded the specs of his beloved Stardust, giving it a flat side, and a more rounded shape with a low edge. Using 7075 Aluminum and YYR’s latest technology, E=mc2 offers power and control, a true successor to the much-adored Stardust.

Released at the same time as the E=mc2, Tatsuya Fujisaka’s Blink has the exact same body but at a lighter 65 grams, compared to the E=mc2’s beefy 69 grams. It makes one wonder why there would be two identical models with the same weight, but once you try them for yourself, you will understand.

It’s the return of the much-loved Stardust; the same yo-yo in two different weights. Will you choose the light and nimble Blink, or the heavier E=mc²?

Please note: YYR uses 7075 aluminium alloy to seek their best performance. 7075 is not a great material for anodizing, so YYR yo-yos have anodizing imperfection and small spots, scratches on their bodies. They seek the best performance, not always the best cosmetics.

BEFORE YOU BUY YYR YO-YOS, PLEASE READ THIS. (Please read the red paragraph)
