I like to check out ebay and see what people are selling, the interesting ones are the items that are haunted. It seems that people used the word "haunted" very loosely and will throw the word on anything they can to make a sale. And unfortunately there's a sucker born every minute.
But this one actually has a good background story and pictures. So maybe it really is a "Dybbuk Box", or the seller went out of his way to tell a story. Either way it's selling.
Here is the description and story regarding this item, and pictures added below.
This is a Dybbuk Box. I purchased it about five months ago from someone  off eBay who claimed the box was "pure evil". I had no intention of  opening the box, but much to my horror, the lock busted open in  shipping. Seeing that the box was already open, I figured I might as  well see what the contents are; There was a lot of old Jewelry with the  initials R.H.C. (the original owner figured out the name of the dybbuk  through his research, and I will reveal the name to the winner), very  old pictures of different places, little jewelry pins, and a few pocket  knifes.  The interior of the box is very interesting as well, it has two  hidden drawers, and upon further inspection of the box I realized it  used to be a music box!  I believe the previous owner had such a  negative experience with the box because he admitted to breaking the box  open and damaging parts of it. When I received the box, I did some EVP  recordings that had little success, however, I found when you touch the  box and interact with it, things begin to happen. As I was in the  process of restoring the box, I was bending over my work bench, and I  received a swift, painful KICK IN MY BACK!!! I nearly fell over. I was  not very happy about this and  four days later I decided to seal the box  with wax, which is the traditional method of sealing a dybbuk. After I  had sealed the box I felt a strange euphoria, and I gave the box a happy  pat and left the room. Upon returning to the room, it smelled  completely of Jasmine, and I have nothing in my room that would generate  that scent. Most recently, my room had been STRUCK BY LIGHTNING (seen  in the pictures) right where I had placed the dybbuk box!!! Everything  in my room was cast aside and knocked over, except for my three reptile  cages, as if the events were controlled and happening around them. After  this event, I moved the box to the garage. A few days later, I took  pictures of the box in my garage and left very quickly and immediately  got into my car to run some errands. However, it took ten minutes to  start the car and I have never had problems with it before. This morning  I went out to my car and found that all the windows were rolled down  and my wallet was in a different place in my house. I don't necessarily  believe this box is "evil" because I have done a fair amount of reading  on Dybbuks, and found that they have their OWN AGENDAS, and they create  these events to let their keepers know that their agenda is taking them  elsewhere now. For obvious reasons, no returns whatsoever. Only ships  within USA
