Some of the aluminum holder was very sharp and this resulted in lacerations. That was for me anyway not the case. The holder was abraded very nice everywhere and aberundet. I even tried to cut me to the thing, no success ^^
The coasters themselves are also processed very well and good. Only the 3 rubber studs on the underside are to complain about. Born babies are not uniformly carried on the same spot and it looks therefore stand little weird (because you see through and can see the mess of rubber studs).
That's for me, but no reason to deduct a point. The article is still good.
