I purchased this new on Amazon for 3,980 yen, but I'm selling it because I can't use screws in my rental apartment. I took it out of the box and tried to fit it once, but I couldn't install it, so it's practically new. I've discarded the box, so I will wrap it in bubble wrap and ship it in simple packaging. 【Chain-Type Roller Screen】 The roller screen fabric is made of 100% thick polyester (2025 version upgrade). The headrail uses aluminum for strength and durability, making it sturdy. The PVC chain type allows for stable and slow rolling compared to the pull-cord type, and it's easy to adjust the light blocking even for large sizes. Also, unlike curtains, which have a presence when hung, roller screens are cylindrical when stored, providing a clean look. •【Usable Locations】 Roller screens can be used in various places such as homes, offices, and stores. They are mainly installed on windows and doors to adjust light and visibility, and to ensure privacy. 【First-Class Light Blocking & OEKO Certification】 Light blocking rate of 99.99% or more. It blocks sunlight. It also has a UV cut effect, preventing deterioration of floors, furniture, etc. due to UV rays. In addition, it suppresses the indoor temperature in summer and blocks cold air in winter, providing insulation and heat retention effects, making it comfortable to spend time in regardless of the season. It also improves the efficiency of air conditioning and can be expected to save energy.
