I've applied lead sheets to the interior of a Danboch Grande. I don't smoke. Purpose of use: Musical instrument performance Production cost: Danboch Grande body ¥151,000, lead sheets ¥44,050, lead tape ¥3,300 If you need it, I'll include the mat under the Danboch. ⚫︎As shown in the third photo, there are some slight bends in the connecting joints. I had applied gap tape. ⚫︎As shown in the 18th photo, the screws in the places marked with ✖️ don't stay in. The parts supporting the side table are all fine. ※ The position of the air vent in the photo was reversed. It's on the right side (Correction) ⚫︎There are many scratches, stains, and traces of tape removal besides those in the photos. ⚫︎As in photos 5 and 6, the plastic in the door joints is cut at the top and bottom, so it's quite fragile. ⚫︎The door rubber comes off every time it's opened and closed. You might be able to fix it by applying the included grease. I was using tape to secure it. ⚫︎When you rub the lead sheets, a little powder gets on your hands. I think it's probably oxidized lead powder. It might not be very good for your health. ⚫︎All the screws are present, but some screw holes are unusable and have been removed. ⚫︎The 17th photo is the underside of the table. ⚫︎I remember that some of the screw holes in the circles were slightly tilted. I think I pushed them back and inserted them. There's no problem with the screws in the circles staying in place. ⚫︎As shown in the 20th photo, there are some places where the lead sheets are torn (on the ceiling). There are also tears on the edges besides those in the photos. ※It's not perfectly applied. I was able to soundproof it to some extent by applying sound-absorbing material. I purchased this item from Mercari at the end of May 2020, which the previous owner had bought, and I used it for about a year before relisting it. I'm listing it at a significantly discounted price due to its defects (*´∀`)♪ Please refrain from purchasing if you are sensitive to such issues, as returns are not accepted. ※Please be aware that cancellations after purchase, complaints about the product after arrival, returns, and returns are not accepted.
