Standard 6 pc. Clamshell Mold
Choose a Variant

Make wax melts and tarts quickly and easily with our crystal-clear clamshell molds. They snap securely shut yet remain easy to open. The Standard 6 pc clamshell holds 2.75 oz. of wax, and is the most common size in the market. Our clamshells accommodate high fragrance loads and pour temps up to 180°.

Recyclable under code 3, which is accepted by most curbside services.

Details: Holds 2.75 oz. (78 g) of wax for all 6 melts. Melt size is 1" (2.5 cm) cubed. 

Pro Tip: If you open the clamshell up all the way and make a crease in the spine, they'll sit nicely on the table without tipping.

Everyone Loves Wax Melts!

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!!

Clamshell hard to open and close

Every item I have ordered from you thus far has been of the highest quality. Unfortunately, I cannot say the same for the Standard Clamshell. It has a gray coloring and is extremely difficult to open and close.

Hello Robert! Thanks for taking the time to leave a product review, although we're so very sorry to hear about your recent experience with the Standard 6-pc Clamshells. We want to help, so a member of our Customer Service team has reached out via email to provide further assistance.

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.

Great if you don't open them...

Positives....they don't leak, standard size clamshell. Negative...and it's a big negative, is that once you close them you literally have to pry them open. I've waited to write this after seeing how most of them are. Every single one has been a disaster to open after closing. I've had to leave one corner popped open to help with this, but that's just not attractive to see in a shop.

The best clamshell I have used so far. I make wax melts a lot. I poured at 140 and never had any issues at all. The only problem I had was when I shifted my clamshells after pouring it gives me a funky surface. Since then, I made sure not to bump into my table after pouring coz this can create a big problem.

Horrible Experience

I poured at 165 degrees and the clamshells started leaking wax. There were cracks in these shells. I'm going to try to get a refund because I have wasted a lot of wax because of these shells.

These are great quality but are not clear.

This is the first time ordering shells from CS. While the quality is awesome be warned that they are not crystal clear. They have a grayish tint to them. I've been making melts for 3 years now and have ordered from a few other places and they are all clear. I now have a huge box of different colored containers that clash with my others.

Just starting out , going from Hobby to Full Business.. I had not really gone into Making Melts but I was surprised with the quality of these . My Candle and Soap Business has now added this as a perfect additional source of revenue .. Thank you for all your support Candle Science.

Easy-to-use and the perfect size! These have quickly become my favorite item to pour and have on hand for my own use, as well as being popular among customers. The plastic is sturdy and they stay shut without being too difficult to open.
