bronners - the juju be bag has the tying straps - but it doesn't have the loops at the base of the bag, does it?

The advantages of the onbag is that the straps are much wider, so they work in the same way as a wrap does (in terms of comfort), and the loops at the base of the bag allow the ties to be threaded through - so that it can be worn like an onbuhimo - effectively it's a bag that can be worn like a carrier.
