Hi,
The Pipe Museum or "het pijpenkabinet" (Prinsengracht 488 ,1017 KH Amsterdam, the Netherlands)
Hajenius
and Hartman Cigars & More (Leidsestraat 58, 1017 PC Amsterdam)
are the most relevant pipe shops in Amsterdam. There should also be a davidoff store, but never went as it is a bit further away then i would like to walk.
The Netherlands have SG blends, but the mainstream blends like FVF, Bothly Flake, etc.
Some Erik Stokkebye blends, Stanwell, Mac Baren, Peterson (small selection), Davidoff pouches, etc.
If you want tobacco i would recommend Hajenius (100gr My Own Blend= 25Euro) they also have a good collection of pipes.
Hartman Cigars, is a small shop, with a smaller pipe range (pipes and tobacco) but they do have some interesting pipes.
The pipe museum has the most pipes (also has estates) in the Netherlands in my opinion and they have Capstan tobaccos with 3+years on them (a few other aged blends, but no rare aged blends).
I would not recommend the tour (15 or 25 euro p/p, if not mistaken) at the Museum, in my opinion it's not worth it. Just a tour of old pipes (such as opium, hungarian, clay pipes, etc). I would also say that they have no or limited knowledge of Artisan pipe history.
Keep CASH on you if you want to buy a pipe from there, they only accept cash.
(not relevant to you, but I DISLIKE the guy. Each interaction with him he had a condecending tone and did give didn't give me time to browse the pipes. Asked him "can i look into the pipe drawers?" and he literally told me "only if you are gonna buy a pipe")
