We can also add a little internal velcro-fastened pouch which contains a removable and re-recordable sound device, shaped like a heart. You can record a message which is played back whenever the device is squeezed. The device is approximately 6.5cm across and can be recorded over as many times as you like.
This is a wonderful way to treasure special messages from loved ones, for the sound of heartbeats or any other treasured recording. You can also use the pouch to pop in any other little mementos.
