Simple cleaning and UMD startup have been confirmed. Shipping via Yu-Packet Post Mini. I strive for a smooth transaction until the very end. Occasionally, there are customers who request returns due to issues such as screen yellowing or loud reading sounds, or because the product differs from the description. Please review the images carefully. Also, prices fluctuate depending on the condition of the item. We do not accept returns to prevent product substitution, so please only purchase if you understand and agree to this policy.
