8 Pack – 6X6″ CD DISC MAILER RIGID ENVELOPES STAY FLATS PLUS WHITE Peel & SealBox has a label that reads: 9 PSW 6″ x 6″ Stayflats Plus White, and is dated 2006. You will receive 8 peel and stick rigid mailers per order. Because they are about 18 years old, I tested the self-stick with a CD in a jewel case, sealed inside the mailer. After 12 days in 20F (outside) to 70F (inside), it was still sealed good. Fast handling, quick ship USPS Ground Advantage. Please ask any questions. Actual item in photos.
