Tutto OK, Amazon sempre una garanzia

works great

If you have a K40(Chinese) laser cutter and happen to crack your focal lens, thats a good and quick replacement. The quality is the same as the original lens that came out of the box.

These were the perfect upgrade to my stock K40 co2 laser. Received the product when stated by seller and in the condition it was advertised. Will buy from again.
