・Instant purchase OK! ・This is a CASIO electronic musical instrument (Digital Horn DH-500). ・I have confirmed that each tone and scale produces sound. ・Several deteriorated capacitors unique to this model have been replaced. (Models that have not had the capacitors replaced are likely to fail in the near future) ・Although it is a product from about 30 years ago, the appearance is relatively clean (personal opinion). ・Power: Uses 5 AA batteries (sold separately), or the AD-1 adapter (sold separately) can be used. (Please prepare the batteries yourself) ・Auto power off: Turns off after 6 minutes of inactivity. ・Shipping is planned via Rakuraku Mercari delivery (Takkyubin) (120 size). ・This is a used item. 　If you are concerned about minor details or are nervous, please refrain from purchasing. ※ Everything in the photos is included. 　　Main unit, mouthpiece, manual (copy), soft case Due to being a victim of return fraud, I will apply a protection seal before shipping. Please check the image of the protection seal. If the seal has been removed, I will not accept any claims. Please note that the seal can be removed by wiping it with alcohol, etc. Please take care of this yourself. In the case of bidders with many negative reviews, I may cancel the bid.
