Here's where the humor comes in. You just know that some bored geek at the toilet paper factory wet his pants (luckily he works at a toilet paper factory!) the day he came up with this product's name... "Myagkii znak" means "soft sign," as opposed to "tvyordii znak," the "hard sign."
A Russian friend was looking through some photos on my computer and did a double-take when she saw I had pictures of toilet paper... I think that only nerdy Russophile blogger friends can understand why I just had to get a photo and write about it!
