I just spent the whole morning trying to figure out what this actually is after a reader sent me the link via email. And after endless rounds of using Google Translate on the Japanese site, this is what I gathered about the Pochi + Hello Kitty Silicone Pouch.
P+G is a Japanese company that specialises in making lifestyle products like wallets, card cases and coin purses out of silicone. Besides adorable coin pouches that come in a dazzling array of colours, they currently have a Hello Kitty limited edition that retails for Y1200 (around SGD18.50 or so). Measuring 92 mm by 45 mm, it is palm-sized, great for loose change and other bits.
There is an online site that seems to take orders, though I am not completely sure if they take international orders. If anyone out there can read Japanese and is able to transact an international order, do kindly leave a comment here. Or if anyone has spotted them anywhere locally, do let me know too.
