Paradise Pen is the only major pen store in Las Vegas. There are a couple of stores that sell a handful of pens, but just as a minor addition to their main stock of stationery and related items.

PP is located on the Strip, in the Fashion Show Mall, so it's easy to find, though you may have to deal with traffic and parking difficulties.

Mazzini47 is a luxury store in Pordenone (North-east of Italy). They sell all kind of elegant and design gifts, from writing instruments, to business bags, to clocks, to leather items.

I really like this shop because of the kindness of its employees, the great quality of its products and the superb customer service.

A stylish shop in the center of Gent that has been in business since 1845.

Offers a wide selection of fountain pens, ink, stationary and leather goods.

Located in the Bank of America (Old Continental Bank Building). Large selection of pens along with restored vintage pens.

A lot of pens and brands, also stationary. Very friendly and helpfull.
Also a lot of special fountain pens.
Worth a visit (near Amsterdam).
