They're easily available in large countries, and the Internet, but i was wondering if they're available here in Pakistan? If so, I've got the following questions.
1. Do they even really work?
2. Where to buy them?
3. Whats their price?
4. The ones that are available here, are they branded or local? or are both available?
5. Displex is a very famous brand, is it available here? If so, at what price?
