I am a bit disappointed that Ranger has discontinued so much of their Melt Art. It took forever to find a melting pot. I wanted more FLEX and that's not to be found at a decent price. Oh well.
Anyway, I did some research and found that glue sticks can be used in the UTEE in place of the FLEX! I hope it works for me because I'm going to try it soon. I'll let you know the results!
