I'm looking to gather more info about your magnetic iron oxide product in the 30-50nm range. Specifically, I'd like to know about its availability, pricing, and any bulk order discounts you might offer. Additionally, could you provide details on the product specifications, including purity levels and packaging options? If you have any datasheets or additional resources, that would be great.
