Abstract

Abstract Sheets for use in correspondence which can be used for postcards, etc. are disclosed. The correspondence sheets consist of twice-folded sheet displaying information on the inside, clear resin films coated on the inside each-other-facing surfaces of the twice-folded sheet in a manner that they can hardly be peeled off, and a temporary adhesive layer which connects the each-other-facing clear resin films in a manner that they can be later peeled off and also the peeled surface thus formed has no tackiness. The sheets will be peeled off at the temporary adhesive layer by the receiver, and the peeled surface on each side after the unfolding is covered with clear resin film having no tackiness.
