This packet of fifty matches costs 1 rupee. The exchange rate is about 45 rupees to $1 USD.  So the packet costs just over $0.02.

HOW IS THIS POSSIBLE?

Sure, they are small and made from wax; nevertheless, the materials alone for fifty matches and a box must cost something. Then figure in the costs of time, overhead and shipping.

Yet, there they are, on sale for 1 rupee a box at every corner store.
