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

These reinforced mailing envelopes are crafted with laminated fiberglass strands sandwiched between kraft paper layers. This unique construction not only offers extra tensile strength but also provides excellent protection against grease, water, and oil. The laminated fiberglass reinforcements make the envelopes highly resistant to tearing, puncturing, and abrasion. Since they are unpadded, these envelopes are cost - effective for mailing. They are ideal for securely sending items that don't need cushioning.

Using these reinforced mailing envelopes is easy. Just open the envelope, place your item inside, and seal it up. When using, make sure your item fits well and isn't too large to cause the envelope to burst. These envelopes are durable, but try to avoid sharp objects pressing against them during handling. For storage, keep them in a dry place away from direct sunlight and humidity. There's no special maintenance required, but if they get dirty, you can gently wipe them with a dry cloth.
