This is the Calibrite Colorchecker Target Holder, model number CCTHLD. It has only been used a few times indoors and is in near-new condition, so you can use it with confidence. Please refer to the images for product confirmation, and feel free to ask any questions in the comments section. I haven't found the time or opportunity to use it, so I'm selling it for 2,500 yen (including shipping)! Don't miss this opportunity!
