[Set of 6 Soundproofing Sheets] Sound-absorbing material size: 30cm x 30cm x 0.9cm thick (weight: 125g), 6 sheets included. Sound-absorbing material material: 100% polyester fiber. [Package] 6 x sound-absorbing/soundproofing sheets, 3M double-sided tape, 1 x Japanese instruction manual, 1 x warranty card. [1-Year Warranty] Includes a one-year manufacturer's warranty from the date of purchase. [Use Anywhere] It can also be used to make your office quieter and your audio recordings cleaner, as well as in professional studios, rehearsal rooms, concert halls, podcasting, churches, home theaters, vocal booths, home studios, etc. [Easy to cut] Our sound-absorbing material and sound-absorbing boards are made from 100% polyester fiber with a high density of 230 kg/m3, so they can be easily cut with scissors or a cutter, and also have sound-absorbing properties.They are cut using high-precision equipment and inspected by staff, which limits the error in the overall thickness of the soundproofing sheet to 9 mm on either side, and they can be processed to fit the required size for indoor walls, pillars, floors, etc. Easy installation with included 3M double-sided tape: 3M double-sided tape is much stronger than regular double-sided tape, which tends to fall off easily. Due to the popularity of our sound-absorbing materials, sound-absorbing boards, and soundproofing sheets, we're offering free 3M double-sided tape for a limited time only! Fixing is easy with push pins, hot melt adhesive, and masking tape, making it ideal for DIY projects in rental properties (the necessary items are sold separately).
