This is the secret to wet-looking mermaid tails and shimmery wings. A must have! It's easy to mix with mica powders as well for a special effect.
This size is my favorite. The larger jars seem to thicken up too much because a little goes a long way with this stuff, and I don't go through it fast enough.
This is what I use in Sculpting a Baby Mermaid to make her tail so shimmery.
