Sharing this with the photographers here..
I remember stumbling across a thread from a member looking for cheap acrylic ice cubes here(because i was searching high and low for some too).. I finally found mine after more then 6mths of searching.. now to continue with my project..
$2 for a pack of 19 small acrylic ice cubes from Daiso(under the gardening section - the cubes are decorations for pots i think). I went to the Daiso outlet at Rivervale Mall. Cheers.
