This is a really nice compact form of sanderianum! I second (or third) the appreciation of the petal twists.
Is that pure sand the Incharm x Shin-Yi? Yours is the only one I've seen of that cross but back in early 2000s there was high expectations of this cross. It was my first flask purchase but the plants disappeared when I finished school and relocated to a different island.
(Edit: re-reading my post made me realize it sounded I was suggesting robbery which was far from what I meant. I meant that I just haven't seen other owners of this cross post pictures)
