Start with the packed item
For a shipping mailer, measure the item as it will actually be packed. Include any inner packaging and describe the required closure. A photograph can help explain the use, but usable dimensions are needed for the quotation.
Define the bag specification
State the width, height, flap arrangement and printing. Discuss whether the seal must be permanent or reopened. Include the item weight and any handling requirements for review with the proposed material.
Compare the same requirements
Check that quotations include the same dimensions, construction, print and quantity. Ask about sample arrangements and confirm charges and timing for the actual order.
