These dust covers are made specifically for a "cricut original expression" machines. These are a must have to keep your machine nice and look stylish at the same time. They use double quilted material so they also protect from scratches better because they are thicker. They have coordinated piping trim added to the ends for that extra special detail. Covers are machine wash but since they are all cotton I highly recommend line dry. They can also easily be hand washed which I recommend.
