These are the beautifully crafted soaps made by Etsy seller RockHoundSoap. Each $5.25 - $7 soap is designed to look like a specific type of geode or crystal. You know, my sophomore year in college I thought about switching my major from BIT (business information technology) to geology. I didn't though, I wound up switching to marketing instead. Then after I finished undergrad I went and got an MBA and now I write dirty jokes on the internet, the end.
Keep going for a bunch more examples of the coolest novelty soaps you'll see all day.
Thanks to PYY, who always washes with the novelty soap in a friend's guest bathroom even if they're clearly meant for display only. Haha, I do the same!
