Hello there!
As the title says, I'm trading the LPP Pool Party Heimerdinger code for a 10€ RP giftcard! It is for EUW, you can instantly redeem it on EUW. But if you play on a different region, you can write a ticket to Riot Support and they will redeem it manually to your account.
If you're interested, PM me here or feel free to add me on Discord >>> im friendly#7169
Thank you for reading~
