Measurements are shown and are approximate.

Gray plush fabric is adorned with clear sequins, giving a shimmery, almost silver look. There are some small areas with no sequins so you can get glimpses of the body color.
There is one small interior open pocket, as shown.
This doesn't look like it was used.
Paper, receipt, and silicon packets are still inside, but there is no strap.
Receipt is dated 2022. 
This was an estate sale purchase, so this is all I know.
