Good day,
We've got to know that your esteemed company is dealing in such
several silicon materials as Silicon Ingot Bricks, IC grade Pot scrap
Tail & Tail, IC grade wafer, IC grade broken wafer etc..., and we would
like to know if your esteemed company still have these materials and can
supply the same regularly as well. And also we would like know the
origin of these material. Kindly let us receive your reply to these.

And if A M products are still available, kindly let us receive your
best offer for the same so we can check out and purchase
if everything is okay

Looking forward to establishing the good business relationship with your
esteemed company, your prompt reply will be highly appreciated.
Thanks and regards,
