Giftionery Delta is a popular stationery store in Osaka, Japan. They have a very wide selection of inks and pens (both domestic and international), including some very nice store-exclusive pens and inks. It’s a must-go if you’re in Osaka, but they also ship internationally. The main site is Delta CO.LTD., and their online shopping site is デザイン文具 STYLE DEE. For those planning a trip to Osaka, I’ve included a map with their location below.
