I'm looking to source some products in two specific color options: black and brown. I'm interested in understanding the range of items you have available in these colors. Please share your catalog or any detailed descriptions of products that meet these criteria, especially if you have variations in material or texture. Additionally, I'd appreciate it if you could provide pricing information, minimum order quantities, and lead times for these color options. If you have any popular models or bestsellers in black and brown, please highlight those as well. Looking forward to your speedy response!
