It'll take one/two more week for arranging C-031(102C). Could we use B-001(803C) insead? Cause we have 100pcs storage only(for C-031). We could use 100pcs C-031 + 50pcs B-001 or 150pcs B-001. Otherwise, we might need to wait 1~2weeks more for producing arranged. Sorry about that & wait for your confirmation.
