Commercial lipstick is poured into molds to obtain a nice, slanted, rounded shape, but sometimes it comes in containers which look similar to chapstick tubes, with the top cut at an angle. I recycled one of those for the lipstick in the crayon picture, but I also used regular chapstick containers I had left over from making my chocolate chapstick
, and tiny little plastic jars. It's a little harder to apply lipstick in a chapstick tube, but tins (or tiny jars) work really well if you have a brush. It's also much easier to pour the hot wax into a tin.
If you really want the real lipstick shape, you can buy molds at various suppliers. Most of these vendors cater to people who are making cosmetics for sale and not for personal use, so they sell trays with fifty or so molds, but Making Cosmetics
sells a three stick mold. I decided I could do without the pretty shape, and stick with something easy and cheap. A good source for chapstick and other containers is called Specialty Bottle
. They do not sell lipstick molds but they have a nice selection of tins, jars, and bottles, and no minimum quantity. Many other vendors sell similar items, and I'm not endorsing (or affiliated with) anybody.
