I purchased this item in D and the cups were much too small. So then I purchased again in DD. They still did not work well and I decided to go with traditional shapewear for better support. Turns out, neither of these two items I purchased are available for return and I cannot use them. What a complete waste of money!

The puzzle was great except a section of the right balloon had pieces that did not fit in the puzzle. Disappointing since I cannot pass it to my neighbors. Recycle material now!

As others have noted, this is an oxidized, brown powder. It can be polished to shine if doing inlay by sanding up tp 600 grit. HOWEVER, the common technique of inlay - filling the void with powder then dripping CA glue (thin super glue, 2-3 cP) over top of the powder does NOT work with this material. The CA beads up and rolls off to the side. I tried to use Super Thin which is intended for this purpose. Guess I'm on to epoxy instead.
