Does your windshield get stuck in the corner of the windshield? The snow spool makes the windshield barrier free and can be attached firmly as shown in the instruction manual, so it is effective for all vehicles. A small amount of snow remains between the wiper stopping position and the snow spail is not effective, but it is also designed to be extruded sequentially and fall down so you can drive safely and comfortably without the wiper failure. Since it is attached to the masking part of the windshield corner, the snow sveil and the snow remaining on the driver side will not enter the field of view at all, so you can check the car. Note: For cars with a minimum of 0.8 inch (2 cm) difference between the pillar and the windshield, it may be difficult to install. Please refer to the website for detailed application instructions at temperatures below 30°F (10°C). http://ww3.ctt.ne.jp/obatech/
