I replied in that other thread where you were asking about the screen capture, and I think a similar setup works here. But to add, I think you need a solid background so the products pop out (so maybe a white or black desk or some fabrics to change the color easily). Also, an even lighting is a must since otherwise it's easy to get unwanted shadows when stuff is above and your hands possibly on the sides. I have that problem often when doing top-down B-roll.
