※ This is a special price limited to the Mercari market! As someone purchased it for 5200 yen, I will not lower the price any further. DAIKEN's Clear Tone 9 102 is a ceiling material that softens unpleasant household noises and the reverberation of sounds within a room. - Brand: DAIKEN - Model Name: Clear Tone 9 102 TA4102 - Size: 9x303x606mm - Number of sheets: 18 sheets - Weight: Approximately 12kg - Application: Soundproofing/Sound absorption material - Color: White - Pattern: Patterned - Regular price: Approximately 5,500 yen/box Remaining stock: 4 boxes One box covers 1 tsubo, approximately 2 tatami mats. How about it for ceiling DIY? Installation is possible with a tacker and adhesive. (It is not possible in a rental property as it is difficult to restore to its original condition.) Although it is new and unopened, it is stored at home, so there may be dents, scratches, and reinforcement/repair with tape on the box, but there are no problems with the product. There is also a possibility of corner chipping during the shipping process. Please understand this before purchasing. Sales will be in sets of 2 boxes, so selling one box is not possible. Immediate purchase is possible. Thank you for your consideration. We are offering a significant discount for a limited time! Thank you very much.
