This morning (March 7, 2011) the Black option for strong and flexible seems to have disappeared from the ordering screen with the appearance of dark grey. Is this intentional? Other pages concerning the available colours seem to indicate that black should still be an option. -- cheers! David Swart
I still see it listed as a material options on the model page, is it the actual order screen that it is missing from? Which item are you seeing this on? Perhaps a hickup as they are adding the new colors, but I'll check to be sure.
As I said, it's gone from the ordering screen. For instance, I'm seeing this with model: 221266 https://www.shapeways.com/model/221266/
It seems you've set the material Black Strong & Flexible on the restricted materials list. You can remove it from the list on the product details page at the right sidebar almost on the bottom.
Thank you so much for your responsiveness - I feel like a dunce. Please keep up your good work. -- Dave
