Made from heavyweight LUX paper stock with a side seam construction, these envelopes are thick and durable, making them perfect for things like photos, letters, mailings, personal mail, or invitations. METALLIC COLOR: If you want a high-quality envelope, this is the item for you. Made from 80 lb. text-weight paper stock, these envelopes are about twice as thick as printer paper. If this shimmery shade of off-white with a touch of yellow/gold isn’t right for you, we offer these envelopes in many other color options that are sure to match your style. PRINTABLE & CUSTOMIZABLE: If you want to customize or label your envelopes, you’re in luck! These envelopes are printable on commercial, digital, and off-set printing presses, so you can have your company logo and branding printed on them. No need to worry about smudging or jamming because these envelopes are made for compatibility with most commercial printer models. PEEL & PRESS SEAL: The self-seal design of these envelopes is perfect for anyone who doesn’t want to lick or use a moistener on every single envelope — it’s a huge time-saver! Simply peel off the protective strip, press, and seal. It couldn't be easier! This type of adhesive is great for business applications, wedding announcements, and personal notes.
