This is the Thin Fabric Auto Blade Holder (holder only, does not include blade)! This auto blade holder will only work with the Brand New Brother Scan N Cut DX, and will not work with all other machines.
The New Brother Scan N Cut DX with the auto blade detects the depth of material on the mat and will automatically adjust the depth and pressure to cut perfectly.
For detailed instructions on the use and care of this, please refer to your machines user manual.
