Everyone has that one friend that is super nit-picky about how things are done if you visit their home. Shoes off at the door, use a coaster, don’t put your coat in a certain place; you still love them, but it can etch on your nerves after a while. If you don’t want to get mad at their requests, why not try make it easier to follow them?

There’s a glass called City Rain that is ingenious, yet simple. It’s a combination of glassware and a concrete cylinder that will keep any table free of water rings. That’s right, no more being told to use a coaster, because your glass will already have a built-in one. The concrete is high-absorption, which means unless you’re deliberately trying to get water on the table, it’s not going to happen. Just one of these glasses will cost you around $51, what with shipping and all. You can dub it as “your glass” that can reside at the residence of your more particular friends.
