Review on 🗄️ Henryu Silicone Container Elves Wax Concentrate Jars - 6ml + Wax Carving Tool (4X6ml), 46ml: Convenient Storage Solution for Concentrates & Bonus Carving Tool Included by Denise Davis

Not much. However, it is not literally airtight. The different shapes and their relationship to each other help me to see what's in which little bag. A great way to store multiple extracts or flowers in one block. I want it to be really FLAT. No rating for this item, but it is approximately 1" tall. Just not something that easily fits in your pocket. Good buy. Good quality and thickness, and the color comes through the silicone. The lid holds tight and never comes off on its own.
