Thank you for viewing. Aclearmat Insulation Material Aclearmat R1.2 with high insulation performance I bought too much and was refused a return at the store, so I am selling it. It has been stored indoors since purchase. Also, after taking the product photos, the top of the packaging opened when I picked it up, possibly due to the way I held it. The contents are new. I will seal it with tape when shipping. - Brand: Aclearmat - Model: R1.2 - Size: 10K 50mm x 430mm x 2,880mm - Quantity: 24 sheets, enough for 9.5 tsubo (approx. 31.4 square meters) - Application: For construction If you pick it up, please do so in Kokubun, Ichikawa City, Chiba Prefecture.
