Long lasting scented mineral oil based Gel Melts for warmers are a great way to enjoy flame-less aromas at home, work and school. Each 1.5 oz cup can give you 30 to 40 hours of aroma when heated properly, we recommend a minimum of 25 watts when using light bulbs. How to use: Remove a teaspoon of gel at a time onto a heated surface. Scent is activated when gel starts to melt. Easier to clean than messy wax tarts. Just cool, peel and discard. Made in USA by The Gel Candle Company since 2005. Scent Description: Cool Spa - Clean and fresh strong.
