10x10 Laser Engraver

Selling this laser engraver, 10 cm by 10 cm, does not cut. Used very few times; I recommend searching online for its specifications. I am unsure what materials it can engrave—paper? Wood????? Hand delivery only in the Sintra area. No exchanges accepted, and I will not respond to offers below my asking price. NO SHIPPING. Cash on delivery—item handed over upon payment.
