Nasty! But, your chances of getting one are only 1/30. And again, tons of people would be willing to trade for another colourway. I mean, I’m not allergic to nickel and I’m certainly hoping to get one.
Also I doubt that YoyoExpert would intnetionally break the seals on any of the blind boxes. And because of their rarity, selling them of separately would be quite unfair to all the other retailers. Plus it would allieviate the curiosity of what you’re going to get.
