Slice Design Cards will cut exclusive shapes & designs in 1" to 4" in 1/2" increments. Several cards are MS+ Design Cards. So ... what IS MS+, you ask? It's a Mirroring, Shadowing PLUS Speed upgrade. The MS+ cards will install the Speed Boost update on your SLICE™ so it will be faster regardless of the Design Card you use. The Mirroring and Shadowing will only work on the MS+ Design Cards.
