Thank you for looking! These are Sansei goggles. I bought them at a field, but I'm selling them because I used them about 3 times and they didn't fit me well. For ease of use, I cut the pre-made rubber band and attached a 100-yen store's mask adjustment cord. To be honest, this was easier to use. The product is waterproof and will be packaged in a transparent bag. If you have any questions about the product, please feel free to contact me(^^)/! *Please refrain from purchasing if you are concerned about minor scratches or dirt as it is stored by an amateur. Material: Plastic, Rubber Brand: Sansei Sport: Airsoft Strap Type: Head Strap This product has passed the Japan Toy Gun Cooperative's goggle safety standards. You can't predict where BB bullets will ricochet. Not only yourself, but everyone in the area where the BB bullets can reach should wear goggles. If a BB bullet enters your eye, you may get seriously injured. *Always use goggles designed for airsoft guns. *These are standard goggles, and I think they are safe for beginners because they are full-face!
