TWINSWOLF Laser Safety Glasses For 405nm Violet Laser Beam 450nm Blue Laser Ray Complete protection 190-490nm Eye Protection Goggles Orange Lens Black Frame CE Certified OD4+ VLT>50% (TUBS2)

They perform very well when the laser is working and allow enough ordinary light in to see what is going on elsewhere. They come in a good quality zip case with a soft cleaning cloth. I am happy with my purchase.
