Nice Product
Bits came packaged in a robust cardboard box with exterior bubble wrapping. Inside, the bits were packaged in a nice wooden box, each individually plastic wrapped. There was also a thank you card from the vendor extending help if required. I haven’t had a chance to use them yet but my initial impression is very good from the care the manufacturer took to protect their product.

Oh yeah. These are some Beauts!
I needed just one of the sizes originally, but the whole set was way more economical. It's beautiful. And I have already used 1/2 of them. Granted I am using them mostly for unconventional purposes-- plaster molds and leather hard clay sculptures. But they seem like they'd hold up great regardless of substrate.
