According to the local distributor of Gransenbon, these cult blushes are currently being phased out from Watsons stores. However, you can still purchase them at Beauty Carousel, where local shipping is free. ;) The store also ships internationally, so if you live overseas but hope to try these, you can easily find them there.
Although there have been rumours of the line being discontinued, there is a fair amount of stock available, as far as I know. Of course, limited edition pieces and the popular 07 Blossom Pink are sold out but there are still a few lovelies to be found. Take a look at 02 Candy Pink; this sweet colour sells well here and is a favourite with many women in Singapore.
