SAMTIAN 40cm Photo Box / Portable Studio / Shooting Booth The size is a square of 40cm x 40cm x 40cm. The LED lights are flickering and the light output has decreased, possibly due to their lifespan. As a bonus, I will include a USB-powered LED ring light. There are no problems with the light output of this one. Manufacturer unknown. Other notes on the photo box: - One of the rubber bands holding the LED lights has broken. - The cover and the AC adapter plug are missing, but there are no problems for domestic use. Due to the above, this is a junk item, listed as "used with scratches and dirt." The LEDs can be removed, so if you replace them with new ones, the photo box can still be used perfectly fine.
