Silhouette Blades & Cutting Mats are consumable items. The blade needs to be replaced when it dulls and the mats will need to be replaced when they lose their tack.
Silhouette blades are available in two colours so that you can keep a separate blade for cutting fabric (blue) and another for cutting other materials (black). The PixScan™ cutting mats are optional and will enable you to digitise original artwork and photos. The Stamp Making Cutting Mat is designed to be used when cutting Silhouette Stamp Material.
