Enchanted ring 

This is so good, very clean too. no idea how the ring is lifted as I so nothing that gives it away, unlike the plastic version. wonderful

Most likely there is a heavy magnet under the pillow and in the square on front of the box. That is why he moves the block at 0:18 and 0:29. On 0:18 when he moves the box you can hear the click of the ring.

Very clever. I have the marketing version of this Box which uses a magnet. So your method has fooled me, well done.
