I'm interested in learning more about the range of Shohan products you offer. Specifically, I'd like to get detailed information on the materials used, available models, and any unique features that set them apart from other brands. It would be great if you could include your pricing options and lead times for bulk orders, as I'm considering potential volume purchases for my business. Additionally, if you have any brochures, catalogs, or specifications available, please send them my way. I'm also curious about your warranty and after-sales support, as these factors will influence my decision. Looking forward to your prompt response with all the relevant details. Thanks a lot!
