Nichibei Refina 45 Honeycomb Screen / Honeycomb Shade. Size: W680 x H2000. Used on a 70cm wide back door. Removed it because I installed an inner window. Used for 3-4 years. Condition of stains: The third picture is the front. Installing it on a back door with low insulation performance will significantly improve the insulation performance. It's from a top-tier manufacturer, so the quality is quite good. I bought it for a little over 30,000 yen. Please understand that this is a used item and is non-refundable, non-returnable, and non-exchangeable (3N).
