How we work

You can walk in, or order from anywhere in Pakistan on WhatsApp. We confirm stock and the total before you pay. Orders inside Karachi arrive in 1–2 days and other cities are served by courier. If you are not sure which part fits your battery, ask us before you order. We would rather answer a question than send the wrong part.
