Gone are the days of messy wax warmers with the No-Mess Tart Cup by Belle Aroma! The No-Mess Tart Cup is a revolutionary addition to wax warmers. This unique cup provides a mess-free fragrance experience while adding a subtle charm with its petal shaped design and soft white color to complement your favorite wax warmer. We found that typical silicone cups leave users with messy residues and uneven melting, so we utilized a high-quality nitrile material to combat these common problems. The nitrile material keeps wax from leaching to the outside and provides even heating to the entire surface. It's also more durable and can be washed for repeated use. You can even toss it in your dishwasher! No-Mess Tart Cups were designed to fit the Bijou Fragrance Vase perfectly, but they can also be used in most fragrance warmers. Available in soft white, they fit seamlessly into most warmers and enhance the overall aesthetic of your home fragrance setup. The No-Mess Tart Cup can be used with wax melts or Belle Aroma No-Mess Fragrance Tarts. It is not intended for use with essential or fragrance oils. Features: High-quality nitrile material Flexible design for easy wax removal Reusable and easy to clean Plastic-free packaging
