Hi Fon,
Thank you for the clarifying questions.
It is new design, not reprint. Some design details are changed. We are still making some change to the design, we will send you the final files for printing tomorrow.
It will be good if we send for printing tomorrow, so that we can get it on 8 Jan. Else it will be too late.
Paper thickness and voucher size is the same as the one we printed last time. I can pass you a sample if you need.
