Jewellery brand Lovebullets has a new item out for Valentine's Day: a pendant containing a paper scroll to deliver a message to your beloved. Sounds familiar? Had someone been inspired by a certain Jewish object on a doorpost?

Publicist Dee Vesali said that during development of the Twist bullet the company had found "incredible similarities" between their concept and "certain ancient traditions". Now they are thinking of extending it to include other inscriptions such as protective prayers and poems.
