To celebrate reaching 100 stores, Seijo Ishii has developed a bag in collaboration with PORTER, with a limited run of 100 items available for sale on the Seijo Ishii e-commerce site. Pre-orders began at 3:00 PM on September 18th. Shipments will begin in early October.

This new tote bag embodies Seijo Ishii's vision of a bag that can be used not only for work but also for shopping, through PORTER's technology and quality. It is black and features a cotton serge front and a PVC-coated back. It will cost 16,900 yen including shipping, and will be sold exclusively on the e-commerce site, Seijo Ishii.com.

Seijo Ishii opened its first store in Setagaya Ward, Tokyo in 1976, and reached 100 stores in March of this year. The online shop, which opened in 2007, offers over 1,200 items, including Seijo Ishii's most popular dessert, the "Homemade Premium Cheesecake," as well as a selection of wines, beers, and sweets from around the world.
