This is a 4K mobile monitor from the manufacturer EVICIV. The image quality is quite beautiful, but I'm selling it because I haven't used it much. I believe I purchased it about 7-8 months ago for around 30,000 yen. It has only been used at home, so it's in relatively good condition, but please understand that it is a used item. A blue light cut screen protector film is applied. If you don't like it, you can replace it yourself, but I will sell it as is. *It is also listed on other flea market sites, so it may be removed or canceled without notice. Thank you for your understanding.
