| Cost and quantity | Review whether mailer boxes needs extra setup, thicker material, inserts, or slower assembly. | Review whether folding cartons reduces setup, storage, or pack-out complexity at the target quantity. |
| Sample risk | Check fit, closure, tolerance, finish alignment, and loaded-product behavior before approval. | Check fold behavior, board direction, artwork position, closure strength, and packed-product tolerance. |
| Material and finish | Use this side when hand-feel, wrap, rigidity, insert fit, or premium finish layers matter most. | Use this side when printed panels, lightweight board, kraft/coated paper choices, or faster finish review matter most. |
| Packing and delivery | Confirm unit weight, assembled volume, packing method, and protection expectation. | Confirm flat/assembled delivery, carton packing, retail shelf handling, and repeat-order needs. |
