Homemade
I wouldn't buy these again for a few reasons.  They appear homemade for several reasons.  The box mine were packed in was too small, and they were stuffed in, so there was some breakdown.  The bath bombs are wrapped in a wax-free paper designed for food service (think the papers at the bakery in your supermarket).  They are sealed with something that turns brown after it is exposed to air, so you see this little brown swipe on all of them.  Also, I left mine in a glass vase in the bathroom, and while the room smells nice, the color on the bath bombs has been fading on the ones left out (those stored in the cabinet did not fade).  I don't think there is really much savings in these.
