10 White Security Envelopes with Left Window and similar items

PLEASE NOTE: If you buy more than one batch, please do NOT ask me to ship them all in the same envelope. I have to ship how it costs me the least for shipping. This is how I can offer such low prices. Batch 1: you will receive 10 left wide window security envelopes. They have clear plastic covers on the windows. The envelopes measure 8.58 inches by 3.6 inches. The window measures 3.7 inches by 1.3 inches. 8 of these only have security paper on the front of the envelope and 2 have security paper on the back and front of the envelope. Batch 2: you will receive 10 left thin window security envelopes. They have clear plastic covers on the windows. The envelopes measure 8.58 inches by 3.5 inches. The window measures 3.35 inches by 1.04 inches. Security paper is both in the back and front. These envelopes have 4 different designs as shown in the picture. Comes from a smoke free and pet free home. I re-use mailing envelopes, boxes, and packaging material in order to keep my prices low.
