Sennelier Transparent Watercolor Iridescent Color 12 Colors Sennelier Paint

This is a 12-color set of Sennelier iridescent watercolors.

[Set Contents]
12 x 10ml tubes, watercolor brush, metal box (lid can be used as a palette)

Each color has been used about twice, and I estimate about 90% remains.
There are minor scuff marks on the lid of the metal box from normal use. Please check the photos.
I am selling this because it was stored away in a drawer.
