Daiso in Plaza Singapura used to some that can be seen at http://www.i8899.com/shop/product_info.php/products_id/159
I'ved checked the Vivocity outlet and they don't have them either. I've seen similar products in toy stores, but at 5-10 times the price (Daiso sells everything at S$2, some Popular bookstores have these for $10-$25).

Does anyone know for sure if the IMM Daiso store has them still, or if there's someplace else that sells them at a similar price(~$3-4 would be ok)? I wouldn't like to make a wasted trip.

Thanks.
