12 1/8 x 9 1/8 x 4 White Easy-Fold Mailers 50/Bundle

These white easy-fold mailers are scored at multiple depths for great flexibility. They let you quickly package items without any carton setup. Just place your product in the middle, fold in the sides to your preferred depth, and seal with tape.

Using these easy - fold mailers is a breeze. First, find a flat surface. Put your item right in the center of the mailer. Then, decide how deep you want to fold the sides based on the size of your product and fold them in. After that, grab some tape and seal it up. As for maintenance, keep them in a dry place away from direct sunlight to prevent any damage to the material. Also, be careful when folding to avoid tearing the mailer. If you have any sharp items, it's a good idea to wrap them in something soft before putting them inside to protect the mailer and ensure a proper seal.
