I'm looking to obtain a quote for 10 bags of fine quartz wool, specifically the type with a strand diameter of approximately 4 microns, each bag weighing 1 kg. Could you provide me with your best pricing options, including any bulk order discounts? Additionally, I would appreciate details on availability, lead time, and shipping costs to my location. If you could also include any relevant specifications or certifications for the quartz wool, that would be great. I'm eager to build a reliable partnership, so please let me know if there are any other products you offer that might complement this order. Looking forward to your prompt response.
