10 x 15 x 2 Expandable White Tyvek Envelopes 100/Case

These envelopes are made from 18 lb. olefin, which makes them ten times stronger than regular paper envelopes. They can expand to easily hold bulky items and come with a convenient self - seal closure.

These expandable white Tyvek envelopes are super easy to use. First, open the self - seal closure. You can then place your bulky items inside with ease, thanks to the expandable design. When you're ready, just press the self - seal to close it up. As for maintenance, they're quite durable, but try to keep them away from sharp objects to prevent any tears. Also, store them in a dry place to keep them in good condition.
