Parcels are packages or bundles of goods that are typically wrapped and sent through postal or courier services. They can vary in size and weight, containing anything from letters to larger items like electronics or clothing. The process of sending a parcel usually involves labeling it with the recipient's address and paying for shipping. In many countries, postal services and private courier companies handle the delivery of parcels. Tracking systems are often available, allowing senders and recipients to monitor the parcel's journey. Proper packaging is essential to protect the contents during transit and ensure they arrive safely.
