Review on Candle Making Molds Set - 12 High-Quality Candle Molds with Bonus 120 ft. Wick - Durable Plastic Molds for Crafting Custom Candles by Wendy Rodriguez

Molds warp with the heat of cast wax, making candles almost impossible to remove. I had a hunch this might happen when I bought them but the reviews seemed favorable so I did it anyway. Freezing candles only aggravates the situation. I had to throw away the two smaller posts and the cone shape as they were completely useless; larger ones can be used with more time and frustration (and if you don't mind slightly crooked candles); Round and egg shapes are fine and I use them quite often. I would not buy this product again.
