Atelier UKAI Tokyo GRANSTA is a shop selling cookies and baked sweets in the Gin no Suzu area of Gransta Tokyo, inside Tokyo Station. Its signature product, the Puruseku, packs several kinds of cookies into a can and emphasizes a melt-in-the-mouth texture and butter aroma. The Tokyo Station-limited Puruseku Assorti can holds eight cookies and keeps for about one month. Cookie cans have short shelf lives, so they are not suited to long storage.
