Seria Shinjuku Marui Annex

"Competition among 100-yen shops, the Japanese equivalent to an American dollar store, is resulting in cool outlets filled with fun items for the home and office. Seria, in particular, has a surprising selection of tableware, kitchenware, stationery, and housewares. DIY fans will have a heyday carefully perusing the selection of things you didn't know existed but now must have, and many items like the tableware items are surprisingly high quality and beautifully designed. Gifts that are easy on the wallet and cool for friends back home include kawaii (cute) washi tape in fun designs, organizers for home and for travel, and other souvenirs. This Seria shop is a short walk from Shinjuku Station, but there are branches throughout the city."
