These little teal envelopes are incredibly handy to have around. They're the perfect size for gift cards, small photos, thank-you notes, or inserts for wedding invitations. Officially called a #17 size, they measure 2 11/16 by 3 11/16 inches. They're made from sturdy 80 lb. text-weight paper, which is about twice as thick as regular printer paper, so they feel substantial and protect what's inside. The back flap has a classic contour design and a strip of moistenable glue – just lick it or use a damp sponge to seal it shut. The vibrant teal color is great for adding a pop to your mailings. They're also printable if you need to add an address or logo. Whether you're a crafter, planning an event, a small business owner, or just someone who likes to be prepared, a pack of 50 of these versatile mini envelopes is always useful.
