12 1/8 x 9 1/8 x 1/2, 1 White Easy-Fold Mailers 50/Bundle

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

Using these mailers is a breeze. First, take out a mailer from the bundle. Place your item right in the middle of the mailer. Then, decide how deep you want to fold the sides according to your item's size and fold them in. Finally, grab some tape and seal it up. As for maintenance, keep them in a dry place to prevent the paper from getting wet and losing its foldability. Also, try not to expose them to sharp objects that could tear the mailer. That's all there is to it!
