Bought on line. Chinese? Japanese? No information.
Thank you for the additional images.
The presented object appears to be a bow and an arrow in a display case. This bow was made in the late 20th century for decorative purposes in China.
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 30 to 80 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.
With kind regards,
