Souvenirs with style
If you want to buy keychains, I love paris shirts and magnets, prices are pretty much stable all over the city (everywhere where you find at least 5 or 6 of these souvenirs shops one next to the other. Don’t buy at “isolated” or non-touristic shops, more expensive, for sure).
If you want to bring some creative, different and original souvenirs back with you, check out L'univers de leo. Yes, you’ll pay a bit more, but it will be worth it!
There are five of them! the most centric one is at 33 rue Saint André des Arts, métro Saint Michel
