Here's is my review of the Nasty Fans 1 gram silver round.
Great artwork for a small round. I'm surprised at the detail. And the fact that the complete Nasty Fans donation address is legible. I like them.
They are slightly smaller than a dime and thinner.
My rounds were shipped in individual plastic bags (as OgNasty has already shown).

Here is a close-up of the obverse and reverse (aka front and back).

The dark area in the bottom-right is a shadow from my hand. I didn't notice until post processing that it was there.

Size comparison with USD quarter and dime. Note the shadows, indicating thickness.
Size comparison with €1 and €0.10 coins. Note the shadows, indicating thickness.

Size comparison with a 1/10 troy ounce gold round. The gold round is about 3 grams. Note the shadows, indicating thickness.
