This is a white metal and plastic tension rod for placing small items. It's the type that wedges into a space, and although I've forgotten the manufacturer, it's very sturdy. I bought it for around 2000 yen. It's compatible with widths from approximately 28 to 43 cm. - Color: White When installed in the dead space of a tall shelf, it eliminates wasted space and reduces stress. Price reduced. Thank you for looking.
