Greeting cards that play songs are truly obnoxious, especially if you’re a mail carrier and they randomly start playing on your route. Talking Envelopes are only slightly less annoying, mostly because they are customizable. These new fangled letter holders will record audio of up to 10 seconds in duration. Making re-gifting acceptable, they can be re-recorded over again, so don’t go writing the recipient’s name on the outside. Your message will plays back when the flap is opened, delivering a few special words…or nasty ones, your call.
