These lip balm containers work exactly like the ones you buy in the store. The wheel at the bottom raises and lowers the lip balm. Making lip balm is surprisingly easy. Once the balm is made, you can pour the lip balm into the containers (use a small funnel to make it easier) then let the balm cool. Once cooled, the balm is ready to use. The containers also allow you to attach a label if you wish in order to sell at craft fairs. The containers can be reused if you wish. We love to make our own lip balm and recommend these containers.
