We recently moved into a new home and the master has a tub. Naturally, we wanted to relax and enjoy it so I ordered these bath bombs. The price was right and there are 12, which is rare because they usually come in boxes of 4 or 6. The couple that I used so far lasted for quite awhile. Sometimes they fizzle for a few seconds and then disappear but these lasted. The scents were nice as well. I felt relax when I got out of the tub and that is the point so I would definitely recommend these bath bombs.
