10 1/2 x 16 - #5 Self-Seal Reinforced Mailer 500/Case

These self - seal reinforced mailers are made with laminated fiberglass strands sandwiched between kraft paper layers. This unique construction provides extra tensile strength and excellent protection against grease, water, and oil. The laminated fiberglass reinforcements also prevent tearing, puncturing, and abrasion. As they are unpadded, these mailers are cost - effective for mailing. They are perfect for securely sending items that don't need cushioning.

How to use: Simply open the self - seal flap, place your item inside, and seal it shut. It's that easy! Note: These mailers are not suitable for items that require cushioning. Avoid using sharp objects near the mailer to prevent damage. Maintenance: Store the mailers in a dry place away from direct sunlight. If they get dirty, you can gently wipe them with a dry cloth.
