12 1/2 x 19 - #6 Self-Seal Reinforced Mailer 250/Case

These self - seal reinforced mailers are a great choice for mailing items that don't need cushioning. They're made by sandwiching laminated fiberglass strands between kraft paper layers. This construction gives them extra tensile strength and top - notch protection against grease, water, and oil. The laminated fiberglass reinforcements also prevent tearing, puncturing, and abrasion. And since they're unpadded, they cost less to mail.

To use these mailers, simply open the self - seal flap, place your item inside, and then seal it shut. They're ideal for sending documents, flat items, or anything that doesn't need cushioning. When handling, be careful not to use sharp objects near the mailer to avoid puncturing it. For storage, keep them in a dry place away from direct sunlight. If they get dirty, you can gently wipe them with a dry cloth. These mailers are durable, but try not to overstuff them to maintain their integrity and protection.
