Sorry I misunderstand that you don't need Punch and Die Holder.
Quotation attached. Since I don't know customs in your country and forwarder will charge you or not, so I wrote a clause that all import taxes and duties outside Japan should be paid by your company.
I attach the your drawing, in the drawing sheet I wrote that corner will not be straight but curve like the one I wrote on it. for the corner, I attach the photo again. Would you please confirm the shape before order.
