Here is my newest tiny digital canvas. I haven’t done any for a few months and completely forgot my past experience with colored pencil on this kind of surface. It is a bit slippery and does not allow to build up really dark darks unless you carefully plan for them from the beginning and use very sharp pencils all the time. Unlike with paper or traditional linen canvas it is not possible to start with lighter colors everywhere and then go darker in as many layers as necessary. Darker colors on a digital canvas start to chip off relatively quickly if you are not careful.
