Scent: Scent: Sweet orange flowers with warm sandalwood and crushed tonka beans. I put these on the backburner for years, but after constant requests from customers and my own friends and family, here we are! I tested a few different formulations and finally came up with the perfect mixture to use in our car diffusers for long last scent! Our diffusers are designed to last approximately 3-4 weeks depending on how they are utilized. I personally love using 2-3 at a time to have a unique blend of fragrances in our family SUV. I highly recommend encouraging your customers to do the same! Sell per piece or as bundles with scent blends you've pre-picked (our customers actually *LOVE* this concept). Diffusers come with a plastic stopper under the cap to prevent leakage. They will come sealed in a cellophane bag with instructions.
