Love Charm Extra Large Microwave Kiln Kit 15 Piece Set for DIY Jewelry Making Tools

Description includes a "glass cutter dry" (this would be the usual cheap, useless cutter), but the photo shows an oil-fille cutter. Which is included?

Can this kiln be used with clay?

What is the actual shelf size of this MWK in inches please?

What size pieces can you fit in this one? I am looking to begin making figurines, and I am not sure if this would be large enough to fit them.
