I purchased this in 2024 as a stock item, but no longer need it, so I'm selling it. The packaging vinyl tore during storage, so it has been opened, but it is unused. Soundproof joint mat 9 pieces Thickness: 2 cm Size per piece: 30 cm (length) x 30 cm (width) Assembled size: 90 cm (length) x 90 cm (width) I will use recycled materials for packaging, but will take care to protect the product from water damage, etc.
