This is a radio bag to protect your precious radio from shocks when traveling to the RC circuit. The interior and exterior are made of tear-resistant nylon, with shock-absorbent material inserted on all sides to shut out external shocks. The interior is a simple single compartment with a single inner pocket, but it has a large capacity with room for a large transmitter. You can also store peripherals such as chargers and spare parts for various uses. This is a very useful radio bag that is reasonably priced and easy to use.
