I have a model number M2W-00003 from Costco but can’t tell if it’s black or platinum. Called Costco and they unfortunately couldn’t help but I think the answer is in the model number. Although this is the only surface pictured as black the description is the same as the silver. My hope is also high it is the only one with the black pen. Although not a tech question, I think the answer is in the model number. Please help as Costco was no help.
