Hey guys i am in need of help. I made an order for a kayfun 3.1 (from cloud9vaping) but neglected to order the extra large tank window. I do not want to pay the heavy postage fees to get one over here but if anyone is making an order anytime soon could they chuck one in and i will certainly reimburse everything. I know its asking a bit much but i thought its worth a shot. Thanks for reading.
