I'm reaching out with an inquiry regarding BAUCHi state products. We're currently assessing options to expand our inventory, and would like to gather more detailed information about the products available under this brand. Specifically, I'm interested in understanding the specifications, pricing, and any volume discounts you might offer. Additionally, if there are different variations or associated accessories, please include that information as well. It would be great to know about the lead times for orders and any shipping options you provide. If you have a catalog or a list of the current offerings, please share it. We're looking to make informed purchasing decisions, and timely responses would be appreciated as we move forward. Thanks for your assistance!
