Address: 21 boulevard Magenta. In the 10th arrondissement. Metro station (Jacques Bonsargent) right in front. I'm a huge fan of this shop. It has been there since 1867, has an incredible selection of pipes, and Marie-Aurélie is the very personable and knowledgeable owner. No tobacco sales, due to an antiquated French law that limits tobacco sales to licensed "Tabacs". Upstairs in the shop is a lovely smoking lounge - limited to members, but you can purchase a 30-day membership for around 15 euros. Lots of YouTube videos on this shop.
