I sent two Wilayah Kutu via mail this morning. One to Perlis and the other to Sarawak. The cost of the stamp, only RM1. Cheap. I think I can start a mail-order business like this. The only problem right now is, will the book be okay once it reaches its destination? I Think it will, lah. I will do my own R&D test tonight just to make sure. Or else, I will invest on a better envelope.
