Here’s an Ikea Jerker accessory (if real) that I’ve never seen before.
Listed in a craigslist ad as “originally for Jerker unit” I think they’re actually not, but they may be a discontinued item that fits Jerker shelves.
Have a look:
Based on the image, I suspect that they’re actually the Ikea Inreda “Bookends” (circa 2008):
Does anyone have a set?
Do they actually fit Ikea Jerker top shelves?
