We could not find an authenticity certificate on the seller’s listing. Japanese swords and fittings are normally papered by the NBTHK (or the NTHK). Without one, the attribution is the seller’s own assessment and has not been independently verified — treat it with caution and ask the dealer about certification before buying.
If, due to our fault, the item differs significantly from its proper condition, the item may be returned. Cooling-off is within one week of the item's arrival.
