The Postal Service has announced plans to release Eastern Tailed-Blue, a butterfly stamp that is nonmachinable and for use on irregularly sized envelopes.
The release date is forthcoming. The square stamp, which is priced at 68 cents, was developed in collaboration with the greeting card industry specifically for oversized or square envelopes.
These types of envelopes cannot pass through the automated postal processing systems and must be hand-canceled and charged a nonmachinable surcharge — even if they weigh less than 1 ounce.
The butterfly stamps will be issued in panes of 20. The words “NON-MACHINABLE SURCHARGE” on the stamp indicate its usage value.
Like a Forever stamp, this stamp will always be valid for the rate printed on it.
The Eastern tailed-blue butterfly is named for the iridescent color of its upper-wing surface.
