I'm reaching out to inquire about the availability and specifications of the Manju product line. I'm particularly interested in understanding the various models you offer, including their unique features, pricing, and any bulk purchase options you might have. Additionally, it would be great to know about the lead times for orders and any discounts for larger quantities. If there are any sample products available for evaluation, please let me know. Looking forward to your prompt response!
