DIY Project:lip balm in a tube

Isn't it frustrating and unhygeinic to use lip balms in pots? I prefer my lip balms (and glosses and other lippies for that matter) to be in tubes.

I used a lip balm tube I've just used up and cleaned it well. I melted the MAC in the microwave then poured it in the tube. I let it harden in the refrigerator. I still have some left over in the pot but I'll transfer it when the tube has been halfway used up.

Neat huh? Thanks to Jen for teaching me how to do this.
