Single item, stackable, can reuse Consignment shop sprite.
*Can be purchased from NPC for 1 Billion Zeny.
*Can be sold to NPC for 1 BIllion Zeny.
Will be used for trades of high amount of zeny, Example: Tao Gunka Card worth 20 Billions, it will be a single trade of 20 Certificate for the card, no need to have alts and whatnot, just single trade.
Current system is cumbersome this will allow high trades without issues.
Thanks.
