Ultra Thick White A1 Envelopes by Desktop Publishing Supplies, Inc. are the strongest, thickest, & most durable envelopes we have ever created. These envelopes are made from a 100lb Text paper stock (38lb Bond, 140gsm)- making them far thicker than the average envelope. This added thickness not only protects, but adds a premium feeling to your final product. These envelopes are great for couples to accompany their wedding invitations as well as companies to use for mailings or greeting card products.

These A1 envelopes measure the standard A1 size of 3 5/8" x 5 1/8". The A1 size works great for pairing with small thank you note cards or RSVP cards measuring 3 1/2" x 5" or less. The back of these envelopes features a booklet style square flap with a standard moisture activated glue adhesive for sealing. The entire envelope is a pure white color and is printable on with your inkjet or laser printer.
