Hi all and @Cleda, I just wanted to chime in that from my experience, Sheen wasn't plasticky feeling to me at all, especially when broken in. It felt actually velvety. I agree with Marco; I do think Tuscania feels similar, just slightly more chewy. It is similar to Balenciaga's leather if that helps.I feel exactly the same about Sheen. The broken in surface looks interesting, and I am drawn to Sea Green/ Magenta. At the same time, it looks like it may feel plasticky or squeaky if I run my fingers over, which I would not like. Also, I know that Sacramento Green or Terracotta will fit my wardrobe better than Sea Green/ Magenta. Therefore, I am also considering it in a Penelope.
Tuscania now looks like something I would like too! Can anyone compare Tuscania with Sheen/ Athene?
Here is a picture with flash of a midnight blue Flora with an Africa Penelope behind it. Under that is a picture of a sage green Athene (Sheen) Demetra...it definitely is coming off a little more shiny, especially the middle, than IRL. Look at the edges of the bag for more accuracy:
