MacDonald has just released a series of glass cup. total 6 colors. Grey, Blue, Green, Purple, Pink, yellow.
When you bought a set plus some coins for extra size, then you can get one for free!!
One day I was walking along WanChai and want to buy a milk shake. When I saw it is free, then I bought a
set. The glass cup is this. 
Today morning, listen to radio, the DJs were discussing the above
. One DJ said when she went to Mac'
and ask for green one, but it seems that blue, green are all sold out. She felt quite disappointed and I also
wonder the famous of this.
I used once, but I want to put a water plant in it coz too many cups in my office already.
