Pure silk, approximately 440 cm in length, with no visible damage. This obi does not have a Daiko certificate, but it is definitely a Daiko obi. Please refrain from purchasing if you are particular about certificates. I will be lowering the price daily, so please purchase when the price reaches your desired amount. I will not respond to price negotiations. I will refuse purchases from overly sensitive and demanding customers who cannot accept slight measurement errors or minor oversights.
