This is a lovely glass dish for holding body dusting powder.
There are styles with or without the fancy glass top.
We have a few sizes on hand that are the perfect size to fit either our standard 5" puff or the larger 6" puff. Occasionally we get in an even bigger size that could probably accommodate the giant sized "Magno" puff which is 7 - 7 1/2" in diameter.
The inventory on this dish may vary a bit (they are vintage) so you may not get the exact glass design shown in the photo, but it will be very close and will have the same diameter opening.
