Mille-feuille sheets are "super versatile deadening sheets" that have both vibration damping and sound absorption properties. 【Differences from Ready-Made/General-Purpose Products】 〜Custom-made directly from the factory〜 ・By using a 3-layer structure of aluminum, butyl rubber, and NBR (synthetic rubber), it simultaneously exhibits "vibration damping," "sound absorption," and "soundproofing" performance! ・By applying it to your car, you can achieve many effects, such as improved sound quality, reduced road noise, quieter cabin, soundproofing, sound insulation, heat shielding, and insulation! ・Large capacity and cut to an easy-to-handle size. We wanted to deliver a higher quality product because it can be used continuously once applied. 【About the Brand】 A car accessories brand from Hokuriku, inspired by the midsummer sea, "NUTS LAMP". (Nuts Lamp) Have a perfect day with your car, sea breeze, and the sound of waves! 【Size】 Approximately 800mm x approximately 500mm per sheet, thickness approximately 7.0mm+ Number of sheets: 6 If you have a desired number of sheets, please inquire in the comment section.

You can freely cut it to the shape of each service hole. Also, because it's a big size, you can apply a large surface with one sheet. 【Impressions】 This is my personal impression of using the Mille-feuille sheets. When applied to the roof, the sound of rain became noticeably quieter. Also, when applied to the floor, road noise was reduced, and the cabin became quieter! 【Caution】 ・Due to the characteristics of butyl rubber, the thickness may be slightly uneven. ・Please understand that there may be a cutting error of ±3%. ・Please understand that there may be a thickness error of ±1mm. ・Please refrain from applying it to areas where water may get on it or areas with high temperatures. Recommended for those who are using Regulex, Real Schild, and other deadening vibration damping sheets, vibration isolators, and damping materials. We support those who are challenging deadening with DIY!
