Compare the usable interior, not just the size name

The selected mailers have documented outer measurements and either inside or usable-space measurements. Compare the stated inside or usable space with your item and confirm how its thickness affects the filled fit before committing to a case. A size label such as #0 does not establish the same usable space across brands. [2] [7] [12] [17] [22] [27] [32] [37] [42] [47]

Choose a construction and order quantity

These picks include paper cushioning and bubble-lined constructions. Use the construction notes to choose what you want to pack with, then compare the selected pack size. Material descriptions alone do not establish protection for your particular accessory or a local recycling route.
