ProMate is a stationery shop, they’ve got a few pricey looking pens here and a huge collection of notebooks. Their whole brand practically revolves around notebooks; notepads, spiral pads, CADpads, memo pads, workbooks, scrapbooks, drawing books, etcetera.
The Racecourse is across the street from Royal College on Reid Avenue (officially Philip Gunewardena). From Independence Avenue you can turn right opposite Maitland Crescent. There's parking. You can also walk here from Independence Square, just follow the road past Sri Lanka Foundation Institute.
