The freight is calculated on the size of A4 document envelop, which means that the charts will be fold in order to put into the envelop.
If you would like the chart to be in roll, the charts and the book will be separated into two package.
And we have to put the charts into a PVC tube which dimension is about 1 meter long, freight is around THB 1,900.00 (exclude the book freight)
Kindly let me know on how would you like me to proceed.
Best Regards,
Boon
