240 Micron Coloured & Clear A4 Transparent Acetate Sheets (1, Red)

Perfect. Just the right thickness, firm but flexible. Suggested by my art teacher, Will Kemp, I'm using it to help me see the very darks and very lights in a scene or picture for painting purposes. I just hold it up and look at the scene or picture through it, and the very darks look darker and the very lights look lighter and the mid-tones all kind of melt together out of the way. Just what I need for initial mapping of the tonal values over all. Brilliant idea and really helps.

i used it to change the colour of my leds in my gaming rig, works perfectly
