Satisfaction is guaranteed.
If you don't like it, return it and the price of the roller set will be refunded. Included with each set is a chart to use to measure the correct amount of polymer clay for each roller size so you can have uniform size beads every time. Also included is an extra roller top, which, when used with the largest of the 3 bases, will give you a lovely small oval shaped bead. Simple care and use instructions are included with this set. International shipping fees may be higher.
