Until now, selling second-hand sports accessories online has presented several obstacles. In principle, shipping costs and the method of payment were a problem and a source of uncertainty for both buyers and sellers, with many fitness-related items being made from materials that are difficult to recycle, such as nylon, polyester or even plastic. The constant production and disposal of such products only contributes to worsen the environmental situation. Reusing them, giving them a second life, is a virtuous act for the planet, which is spared the generation of more waste. It is therefore an act of conscience to sell second-hand sporting goods online, as it can be a much-needed respite for the planet.
