Thank you for your answer. 
Several hours ago I was browsing the forum and one post also confirms this, I think so. Funny is that so seller says it's 100% original product, but he don't remember where he was buyed !

Those stickers are quite common on Chinese imitations most noticeably they are missing the Stone Age Gamer tag as well as the Krikzz logo I presume as that design was based off the American version.
It becomes a lot harder if you are inside Europe as that logo is used on every ebay listing confirming it is an original product... after all with the removal of the China Ver lettering at least letting the consumer know it isn't genuine after all it retains is the SD2SNES logo which is so well made with its0 glossy black sticker you could never tell it was fake unless you came to Retro Towers the manufacturer for 100% official products in the UK.
