10 x 13 Yellow Tyvek Envelopes 100/Case

These vibrant yellow envelopes are a great way to make your mailings pop. Made from 14 lb. olefin, they're ten times stronger than regular paper envelopes. They come with a convenient self - seal closure for easy use.

To use these envelopes, simply place your item inside and press the self - seal closure firmly to seal it shut. When handling, be careful not to scratch the surface to keep the envelope looking good. Store them in a dry place away from direct sunlight. If they get dirty, you can gently wipe them with a damp cloth. That's all there is to it for using and taking care of these envelopes!
