Where to buy buckwheat pillow in sg?

Recently I read a lot of reviews where there are little bugs found after open the buckwheat pillows. There is another alternative purchase to have the same function as buckwheat pillows, to provide secure feeling for baby when placing on baby's tummy, the latex bean pillow. You can purchase from this website and it costs less than $30. http://www.mumsfairy.com/products/babylove-baby-organic-pillow-latex
