Elite Straight Cutter, Acrylic, Multicolour, 6x7x2 cm

Does this work with the 301S guides?

Is this palstic or aluminum?

Is the blade length adustable? I just need to cut cover stock paper.

The package says that it comes with 5 blades and instructions. There are no blades in the package that was sent to me. Where are the 5 blades?
