Thank you for viewing! This is a set of 5 slightly imperfect high-quality obi cores. There are wrinkles, slight stains, and small holes, but they are not quite "B-grade," so we are offering them as an "AB-grade 5-piece set." This is a great deal for a set of 5, so please take advantage of this opportunity! Obi core prices are currently rising, so I believe this is a very good value. Please note that the types are mixed. Thickness: Slightly thinner than medium (for both fukuro obi and Nagoya obi) Length: Approximately 476 cm Width: Approximately 34-35 cm Material: 100% cotton, pre-washed, shrink-resistant, and anti-mold treated Production area: Okazaki City, Aichi Prefecture #ObiCore #MikawaObiCore #FukuroObiCore #DefectiveObiCoreABGradeObiCore
