We have MANY pixos sets; I got my 6 yr old this one for her birthday along with several of the refills. This is not a necessary item to have, you can simply buy the cheaper refills and the only thing that will not come with is the dispenser which should be thrown away anyway. It doesn't work, constantly gets stuck, and we end up dumping the pixos in a dish and using our fingers or keeping them in the packets and gently dumping the packets into the molds. They take much loner than 30 min to set, I like to let them set several hours or overnight actually. The little faces are cute, however, have superglue on hand to make them stay permanently, they WILL fall off ... often.
