If not, I would purchase Vis a Vis dry erase pens (Make sure not to purchase wet erase pens as they are different - I would also recommend purchasing more than 1, maybe a 5 pack). When you do that, you can purchase some overhead trasparencies and tape these to cardboard, or to printer paper (to give a white background) to make your own scratch pad.
So you need dry erase pens and a white board or overhead transparencies. I'm sure someone will ship these items to your location!
This indeed seems to be pretty good alternative. Thanks GMATLA for the alternate tip.
This time its personal..
