My Nintendo is opening the physical product flood gates again: and I think some fans are going to dig what's on offer, even if it's yet another stationary item.
Yep, it's none other than the iconic invitations themselves, as you can pick up "Super Smash Bros. Ultimate Invitation Greeting Card Sets" for 400 Platinum Points. The set includes three cards (white/green/blue), envelopes, and stickers (seals). These are about in line with the triple holiday card set (Mario, Peach, Bowser) that recently went on sale for 300 Platinum Points.
Nintendo also added in a "Splatoon 2 / Super Mario Splatfest" keychain set, which features two keychains: a mushroom and a star with ink on them. These are in honor of this week's Splatfest, which, by the way, counts as a Mario mission for the upcoming second pin set. The keychain set is 350 Platinum Points.
If you really want either of these, remember that we have a comprehensive guide for earning points (that's been recently updated) here. You can go from zero platinum to picking these two items up in very little time if you don't have a My Nintendo account yet. Just remember that you have to pay for shipping (roughly $5); though grouping multiple items together is possible.
