We've purchased clamshells from a few different suppliers, by far, we are pleased with the ones from Candlescience. They look great and they perform well. They are sturdy, even squares, and holds the wax nicely. We've never had any issues releasing or popping the melts out of the container. We will continue to purchase and we highly recommend Candlescience.

The only thing that I do not like about these clamshells is that they have a blue-ish tint to them. They are not completely clear. They are also a bit difficult to open once closed. Other than those things, they are very nice, sturdy, and serves its purpose!

These are always a hit at my markets! A great option to include in your fragrance lines. They are a tad difficult to open at first but loosen up as they are used.

Sturdy, thick plastic. Provides a nice professional looking wax melt!!

Easy to use, durable, and supports relatively high temps. I usually pour into these around 160-170F and no issues. With a little bending they lay relatively flat (although the weight of the liquid will keep it flat as you finish pouring). No issues with opening after closing them. Just takes a little force, but it's a tight plastic seal, which is what you want. Helps prevent the scent from escaping. Also the price is great so I will keep buying these. I wish CandleScience sold more varieties of clamshells, either in larger pieces for more volume, or in circle shaped clamshells. But this works for my business and my customers love them.
