When you hold it you can feel it's made of high quality 300 gsm metallic card stock. Actually it has 3 layers of it in the middle panel.
Since it's made with a faux seal in the medieval letter style you can order it with or without outer envelope. How about having it addressed on the back, adding a stamp and mailing it as its is?
Formatul scisoare-plic inspirata din scrisorile medievale permite trimiterea prin posta asa cum este. Scrii adresa pe verso, timbrezi si trimiti :)
