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)

why I like YYR E=mc2. cause this yoyo have shape makes me want to have it. I actually prefer YYR OVERDRIVE, cause I really like the style of Ryota Ogi at playing Yo-Yo, and overdrive also makes me want to have it, not only because Ryota ogi, but also cause of its interesting.. SInce no YYR OVERDRIVE in STOREWIND, so I chose YYR E = mc2, because its shape looks cool if played, And also cause I look Hiro Irifune use n played that Yo-Yo (YYR E=mc2), n thats look so good n cool, then I chose that Yo-Yo as I want most this year. :D
