Hi! The palm pillar I had that slides right out is from candlesandsuplies.com I use another one from a different supplier right now because the case price is $20 cheaper with shipping. any other ? feel free to PM me!
Not a dumb question at all, we all were once starting out with this stuff! Submitting usually means just sending in photos of your products. Some places do also want to see your display setup.
I'm trying some of theirs right now. I found one I love-Grapefruit Vanilla Twist! It's awesome. I just poured the Blackraspberry Vanilla & Cranberry Orange, so far they smell really good. Hope this helps a little!
You should test them yourself just to be sure! i don't get them from there but some from some other places say they are gel safe but eventually they end up getting cloudy. Best to do your own tests.
