我是一名常驻中国的室内设计师。当时我正在为一位客户的办公室寻找正宗的日本藏品,偶然了解到了Supein Nihonto。我们当时专门想找两套武士铠甲,将其作为空间的视觉核心。 整个合作过程中,埃里克提供了极大的帮助。他解答了我关于铠甲的各类疑问,包括铠甲的历史背景、尺寸规格、陈列方式以及物流运输等问题。尽管我们身处不同国家,他把所有事宜都处理得清晰明了。 铠甲如期送达,摆放在完工后的办公室里效果十分惊艳。最重要的是,我的客户对最终效果非常满意。 这次合作体验极佳。今后如果有室内设计项目需要采购正宗日本古董,我一定会再次选择这家。

Compré una armadura Gusoku y todo muy bien, tenía algunas preguntas y Eric ha sido capaz de contestar todo lo que no sabía, llegó todo muy bien embalado y bastante rápido. El Kabuto es muy bonito y está muy bien conservado.

J'ai pu échanger de visu avec Eric. C'est un vrai passionné, qui maîtrise son sujet. Je le recommande vivement, surtout dans ce milieu ou le meilleur se mélange avec les pires escrocs

Hervorragende Dienstleistung, Qualität und persönliche Betreuung! Ich habe bereits drei Stücke von Supein Nihonto gekauft und hatte nie Probleme. Nach schlechten Erfahrungen mit anderen japanischen Händlern – lange Lieferzeiten und sogar ein verlorenes Paket – bin ich zu dieser Firma gewechselt. Ich werde ihnen treu bleiben und meine bereits beeindruckende Sammlung weiter ausbauen.

Ho acquistato da Eric un’armatura samurai di grande fascino e qualità, e l’esperienza è stata eccellente sotto ogni aspetto. Fin dal primo contatto si è dimostrato estremamente professionale, competente e disponibile nel fornire tutte le informazioni richieste, accompagnandomi con trasparenza durante l’intero processo di acquisto. L’oggetto ricevuto corrisponde perfettamente alla descrizione e alle aspettative, con una cura nei dettagli che testimonia una profonda conoscenza del settore. Ho particolarmente apprezzato la serietà, la correttezza commerciale e l’attenzione riservata al cliente, qualità oggi sempre più rare da trovare. La spedizione è stata accurata e l’armatura è arrivata in perfette condizioni. Consiglio vivamente Eric a collezionisti, appassionati di arte e cultura giapponese e a chiunque sia alla ricerca di oggetti autentici e di alto livello. Grazie ancora per questa splendida acquisizione che rappresenta uno dei pezzi più interessanti della mia collezione. Mik – Roma, Italia

I had an excellent experience with Supein Nihoto. I purchased a katana and a wakizashi, and both pieces are truly beautiful — carefully selected and of remarkable quality. You can immediately see the attention to detail and the seller’s passion for what he offers. The packaging was also exceptional: all the documentation was perfectly arranged in a refined envelope, which added a very elegant touch to the whole experience. As a thoughtful gesture, he even included a small katana kake stand as a gift, which I greatly appreciated. Beyond the objects themselves, the seller was very helpful, responsive, and clearly knowledgeable. His selection is outstanding, and you can tell he deals in genuinely fine items. Highly recommended — I would definitely purchase from Supein Nihoto again

I received a beautiful tokubetsu hozon nihonto for Christmas from Supein. Actually my wife purchased the sword after receiving some helpful hints and recommendations lol. She knows absolutely nothing about nihonto but Supein walked her through everything honestly and I ended up with something beyond my dreams and expectations, honestly. The packing was exceptional, shipping fast and the sword itself a literal work of art. Supein has a lifetime customer now as my collection grows. Thank you!
