The whole point of wrapping gifts is so they will be a surprise....not so people can peel back the paper and peek.  Now when they get too close, you'll be on first alert with flashing lights and siren, with the amazing GIFT ALARM!  This is just too funny!  It's motion activated so you can hide it in the closet, under the bed or right under the Christmas Tree!

It sells for $13 on this web page:

It's a fun joke and novelty online retailer, so don't take them seriously where it says "Couple this with a stun gun for complete present protection!"
