Rolling briefcases are cases that remain equipped with wheels. The wheels facilitate the briefcases to be rolled to places by the person carrying them. This has multiple uses. The first and the most important of the uses is that it helps in preventing any kind of damage to the human vertebra. Burdens carried for long o the back have a detrimental effect on the bones. Musculoskeletal disorders are also very common in people who carry loads for long time. Pulling a rolling briefcase does not put any pressure on the human spine as the weight is placed on the wheels and the load gets distributed making it easy to pull the heavy weight.
