Thank you for viewing my listing!

I received these from an acquaintance but have kept them stored in a dark place without using them.
Since I won't have an opportunity to use them, I'm listing them for sale!
The included mounting pins are missing, so only the boards are included. This is why I've significantly reduced the price. You can purchase pins online or at 100-yen shops.

【Approximately 2.5 Times Improved Sound Absorption Effect】The sound absorption effect of soundproofing material is determined by the density of the board material. The higher the density, the better the sound absorption and soundproofing effect. By increasing the density of the board material to approximately 200kg/m3, the sound absorption effect reaches about 2.5 times that of other companies' products, allowing you to enjoy high-quality, clear audio.
【Carefully Selected Materials】YOPIN sound absorbing boards are made from environmentally friendly, flame-retardant, high-quality polyester fiber. They are odorless and not only excel in sound absorption but can also be used as insulation and heat retention materials. They improve air conditioner efficiency and achieve energy-saving effects. They are delivered uncompressed, so they are ready for immediate use.
【Wide Range of Applications】The sound absorbing panels come with mounting pins for easy installation on walls, doors, and ceilings. Since they use pins, they can be removed without damaging walls. They are widely used in bedrooms, piano practice rooms, recording studios, offices, conference rooms, and more.
【Advice】For ideal sound absorption, it is recommended to cover over 70% of the room's walls with sound absorbing sheets. Furthermore, for even better sound absorption, we recommend using them in combination with YOPIN soundproofing materials.
