Really first class shop, with a wide stock and very friendly staff
Pen & Pencil
Small, but well located and with some interesting stock.
Reid's
Good selection of pens and stationery, also party supplies.
Most of the staff is quite knowledgeable.
They have parking in the back.
Stationery World
An unassuming little store just up the hill from College Green. Stocks a good (for the UK) range of pens with a reasonable selection of inks and paper (including Rhodia and Clairefontaine). Friendly staff but not always very up to speed on pens outside of the mainstream brands and standard selections therein.
