These items are found through internet. Do not ask me where to buy since I do not know. :)
But when surfing, I find these Japanese sites have many good things for Laputa to shop. You can have a good look.
Messe World: Main Page, Laputa Page
ZooNet: Laputa Page 1, Laputa Page 2, Laputa Page 3, Laputa Page Tokei
