Using this model is easy. Just take it out of the original box and foam carefully. Since it has no couplers installed, if you want to connect it to other models, you'll need to install the couplers yourself. When handling it, be gentle as it's a fragile item, especially because it's a brass model. For maintenance, keep it in a dry and clean place to prevent further tarnish. If it gets dirty, you can use a soft, dry cloth to wipe it. Don't use any harsh chemicals as they may damage the model. And remember, if you're not satisfied with your purchase, you can return it within 30 days for a full refund, just pay for the return shipping (unless the item arrived damaged).
