I was on the fence about purchasing these, but ended up buying them for a Valentine's gift to myself after seeing them in a Buzzfeed article. I wouldn't say they are life changing, but are bath bombs really ever? As a dedicated shower-er the only thing I miss about taking baths is all of the fancy accoutrements that go along with it. This is a great solution - I can feel a little snazzy and do ~self care~ while standing up!I am also not someone who spends too long in the shower, so these last me more than one, which stretches your investment. (Considering the bombs cost $1.25 each when I purchased them, this was not originally a concern, but a nice perk) I was able to give a few away to friends as well, because 16 is quite a few shower bombs for someone whose *luxurious* showers are few and far between.Finally, considering that I was not using an entire bomb per shower, I was worried that leaving it on the shower floor overnight could result in staining, but as others have said, this has not been a problem for me. I also have not had an issue storing them in my shower (pictured above). I did unwrap each bomb for easier access and they have stayed quite nicely in my airtight jar.
