I believe this item was purchased as an authentic product, and I will definitely include an "Anshin Kantei" (Authenticity Verification) service. I received this item when I passed a certification exam, and I haven't used it since, so in my subjective opinion, it's in excellent condition. Inside: No noticeable scratches or stains Outside: No noticeable scratches or stains Serial number: CA1006 The box and instruction manual are also included. There appears to be a stain-like shadow on the box. It's unclear whether this was present originally or occurred during storage, but please judge from the images. Shipping is planned via "Nekopos" (a Japanese delivery service). The inclusion or exclusion of the "Anshin Kantei" service can be changed according to the buyer's preference.
