inquiry to Cashmere yarn Nm 200/2

Good day, I am looking for a small amount of cashmere yarn Nm 200/2, like a sample cone of 100 or 200 gr, color natural white (undyed). I don't have a company but I don't know where else to get a cashmere yarn this fine as it isn't available retail, and I am willing to pay all the expenses. Some friends of mine are also interested so I might even order more if you can supply it, but probably not more than 1 kilo total. The purpose of the yarn is hand-weaving and fine lace knitting. Shipping would be to Belgium. Thank you for your reply. Luc Cuvelier
