This model can be used as a snow shield for external use. It can be used as a snow shield in winter and a sun shield in summer. Originally, I wanted to choose 150*80,(25 for each ear, actually 200*70) although it is only 10cm, the cutting relationship, the cost is much higher than that of 70, so it can only be done. After all, this one is sold as a basic style. There are also customized high-end goods on the 10th, and two of them are enough, therefore, basic style is still cheaper. I hope you can understand. This binaural has been improved, put in the wooden strip to prevent thieves from pulling it away
