These silicone resin molds are really cool! I'm pleased that they're bigger than I'd expected, which makes them that much more useful. This set comes with three trinket box molds with lids: a hexagon, a circle and a square. They're pretty easy to use and really fun to experiment with. I like using mica powder and alcohol inks to add vibrant colors.
The silicone is strong and durable, yet flexible, allowing the hardened mold to easily be removed. When you're dealing with inevitable air bubbles, use a heat gun or hair dryer to gently remove them before letting the mold harden. Make sure you're working in a well ventilated space.
Just a note: this set does NOT come with any kind of instructions or tips, so I wouldn't get this if it's your first time using art resin, or if you're giving this as a gift to a beginner. Otherwise, it's a great silicone mold set for making homemade gifts!
