Yes- majority of companies/ people who sell the soy drops sell them in different amounts. like 1 oz, 3 oz, and so on. And they work just like tarts- you just put them in a warmer. They just melt faster & they are so CUTE! Also I have seen it where they are like potpourri- where you can just scoop the amount you want- and you have the option of mixing the different scents... They are really neat though! Natasha Wisler
