don't laught, because I can't find to buy real molds here, I use my fantasy and make molds from plastic bowl. the small is 22cm x 6,5 cm (3 wicks) the big is 36cm x 6,5 cm (4 wicks) I put a pocket with 25 cigarettes inside to see the shape sorry about cm , but we use m, cm, mm in Europe and I don't know other metric system
