This large float boat will make even the largest bath bomb float with its extra wide diameter! The bath bomb in the video weighs 10oz! This will also work with round bath bombs! Just placed it in the center of the boat in the large hole in the middle☺️ These work so nicely and will last you for years to come if you take care of it! I recommend using with Southern Fleek Bath Bombs😜😋 But will work with any bath bomb! I print these to order!
