I've been going here for years since I was a student at McGill. It has THE BEST collection of office/pen/stationary supplies. I go here every time I go to Montreal to stock up. The staff is very knowledgeable and kind if you would like assistance searching for a particular item. This place is a gem. Yes, it's expensive, but it couldn't be more worth it. They have products that can't be purchased anywhere else in Canada or the US. It's heaven.
