Music Envelopes

All are provided with the same sound.

A very sturdy envelope made of solid cardboard, printed in full color. The concealed sound module is activated as soon as the recipient opens the envelope. The envelope produces a very clear sound, partly due to the effect of the envelope, which now also functions as a sound box. The cardboard envelopes include an adhesive closure (peel & seal closing strip) and can be easily opened by the recipient with a read-tear strip. This offers optimal shock absorption.
