I'm looking to get pricing and specifications for 7 filing cabinets to meet our office needs. Ideally, I would appreciate details on the materials used, dimensions, available colors, and any unique features or locking mechanisms that come with them. Additionally, please share information about your lead times for delivery and any quantity discounts that could apply. If you have different styles or models available, I'd love to see those options, as we want to ensure the best fit for our workspace.
