Where to buy buckwheat pillow in sg?

I bought mine from Qoo10.sg. It's pretty good and it came with a complimentary cover. It retails for $35.90 but I used some of my coupons and paid about $30 for it in the end. http://list.qoo10.sg/item/SOBAKAWA-BUCKWHEAT-PILLOW-SILK-QUILT-HUSK-HULL-BEAN-SPROUT-COVER/408716384 Pupsik sells it as well at $25.90. This one is more suited for babies, size wise while the one above is bigger and more for adults. http://www.pupsikstudio.com/pupsik-beansprout-pillows.html
