For being made of cardboard, Lunt put in more quality and became my favorite of all four types of glasses I used during the hour before and the minutes after the total eclipse. The lens shape held up to handling and passing around several times. It let in slightly more light and less added halos than the other cardboard or even the other hard framed glasses that cost twice as much. The print had the full "ISO 12312-2" code, whereas others just "ISO / CE" which could mean anything.

They came in good condition. I haven’t tested them yet since I need to pack them first and didn’t want to open the package till after my flight.
