I'm looking to purchase a medium-sized product in black. Could you please provide me with the available options for this specific color and size? It would be great if you could include details like material, pricing, and any minimum order quantities. Additionally, if there are any variations or related products you think I might be interested in, feel free to share those as well. I'm keen on exploring what's available and making a decision soon, so a prompt response would be appreciated. Thank you!
