Standard white envelopes can be thin, leaving your mail at risk for tampering. Why not go with quality custom printed #9 business envelopes with an interior black tint from The Supplies Shops? Our white envelopes have an interior black tint that prevents would-be criminals from viewing what’s inside. These black-interior custom envelopes are a smart choice for mailing checks or sending sensitive documents. 

These envelopes feature 24-pound white wove paper stock and a remoistening standard seal. We sell them in boxes of 500, but if you use them often, you may want to stock up and take advantage of our volume savings. We also offer complimentary shipping on orders over $99.

The Supplies Shops has in-house custom printing services to personalize your envelope order. A printed envelope looks professional, but it also saves you time, which can make a big difference when it comes to bulk mailings for your business.
