It looks like one of the types of incense burners (copal pine resin), but I agree it looks more like a tourist item to me.
If you want to see some pictures of them you can google Mayan Incense Burner and check out the images, most will be larger stationary pots, but the hand held ones are there.
If you google the Spanish name you'll see more relevant pictures.
