The formulation in our new Bubble Dust is identical to our Tub Scrubber Bubbling Bath Bombs with one important difference… it simply has not been run through our bath bomb press. Why? Well, for starters, on our end Bubble Dust is far less work intensive than making individually pressed bombs. On the customer’s end you can use as much or as little as you want. We recommend a minimum usage that would be roughly equivalent to one bath bomb or one-third cup. One bag of Bubble Dust contains the same amount of product as 8 – 10 pressed bath bombs. That number of bath bombs would cost $28 -$35!!! So a bag of Bubble Dust at $12.95 is an incredible bargain! Comes in layered scents of Island Coconut, Sugarplum, Lime Verbena and Mango & Papaya.
