A few reasons why I think these Crumpled City Maps are just absolutely brilliant:

1. Duh, we’re talking maps here.
2. You can just cram them into your pocket.
3. There are versions of various cool cities like New York, Amsterdam, Berlin & Sydney.
4. You can compose your own Collection Box of 5 cities to start with.
5. The design and the fresh colours of the whole thing are just amazing!
6. The material is waterproof, so the maps can probably endure more rain on your city trip than you can.
7. You can buy the maps online.

Gotta love them. Emanuele Pizzolorusso did a very, very good job designing these!
