sorry for reply late
I must wait for my client try your sample first
and then we will decide
It's a pity that you can't make WB-2043 with the groove 12mm
that kind of product is very popular here
we have been the supplier of it for nearly 2 years
but we have got a lot of orders for that
pls wait until I have answer from the client and then I will let you know soon
have a nice day!
