Hey folks Im new and first purchase, package came in couple days ago but only had the time to come back and grab it today, noticed there was more than I ordered… I ordered TUTH, ammox2, IS and IH and A314 and realised how come there’s an extra one? MX423… googled it and landed here. Kinda confused. What am I supposed to do with it? Looks like a freebie! Handwritten note “Hi <name> enjoy the gift!!” =D
