11b Envelopes (90 x 145mm)

11B Envelope Dimensions - popular for wedding invitation envelopes and corporate events.

Premium 11B Envelopes - In Stock - Fast Shipping from Sydney, Australia!

Our 11B banker flap envelopes measure 90x145mm and are available in 50+ metallic and non metallic colours. Widely used as wedding invitation envelopes to hold RSVP Cards and to send small thank you cards. The 11B is the smallest size Australia Post accepts as a standard letter. This is the smallest size we sell/recommended because smaller envelopes attract higher postage rates and can get jammed in the mail sorting machinery. All of our envelopes are made in Sydney Australia! If we don't have it, we can most likely order them for you.

Save BIG with our cheap prices and get them fast - direct from warehouse in Sydney, Australia!
