Buy About Coffee and rice husk

RFQ Details

Good pm, I'm Redison L. Tibayan, currently taking Architecture course in De La Salle University - Dasmari�as. I'm conducting a thesis study about utilizing coffee husk as a replacement for sand in glass composition. I would like to ask the costing, or average price of Coffee Husk available in your company, and I'm also willing to order. Hoping for your reply. What is the MOQ? Are you offering free sample of this product or may i know the sample cost?
