Few days ago, bought a new pillow and DS commented that none is as nice as the one he slept on in Japan last Dec. He claimed that he slept really soundly and requested for it. (I have let DS tried many types all these years but he has never really liked any in particular)
As it's a few months back and I had not paid much attention then, couldn't remember. DS mentioned that it's like there's cushion on one side and beads on the other.
Based on DS description, googled and the closest seems to be made from buckwheat / corma beads.
Any one has any idea? Or know of any shop in Singapore that sells pillows from Japan?
