Using this beverage holder is super easy. First, find a suitable spot on the edge of your desk. Then, clamp the holder firmly onto the desk. You can then place your cup in the holder. Make sure the cup fits well to prevent it from tipping. When it comes to maintenance, simply wipe it with a damp cloth if it gets dirty. Avoid using harsh chemicals as they might damage the holder. Also, don't over - tighten the clamp as it could cause damage to your desk or the holder itself.
