When Stretched, the Monet Pro frams is 1-1/2" deep. The 1/2" space between the bar and canvas ensures the user will not pick up a relief rubbing of the stretcher bar, no matter how aggressive the painting techniques used. This Text will have an extremely detailed description of stretcher bars, also will have multiple times in different colors indicating the pack size of 3. Possibly if we can't figure out how to show shipping prices, we will have a chart here telling you how much to be expecting. Brief description of canvas but very vague because that was already picked out.
