As an effect of this craving, I had my online research about this product. And here it is:

From Wikipedia.org:

Hello Panda is a brand of Japanese biscuit, manufactured by Meiji Seika. Each biscuit consists of a small hollow shortbread layer, filled with either Milk cream, strawberry, peanut butter or chocolate filling; chocolate is the most commonly available variety. Recently a yellow-boxed version containing the biscuits with a chocolate shell (instead of the usual shortbread) was released.

It was first released in Japan during the Summer of 1979. Printed on the biscuits are cartoon style depictions of giant pandas.

Hello Panda was originally baked in Japan by Meiji Seika, but production later began in Singapore, Philippines and Indonesia.[1] The Singapore bakery facilities started producing other Meiji products in 1974. The biscuits are exported to most developed countries, such as the United States.

The biscuits are commonly sold in a tall, hexagonal box with 2 oz or 57.5 g. In some countries, Hello Panda biscuits are available in small 21 and 35g aluminum pouches, as well as 350g boxes and 450g tins.

And here are some images from Meiji.com.sg:

You guys should also try Hello Panda, though I’m sure most of you were already eating this product. Yipee!
