Review on MroMax M5X20Mm Zinc Plating Carbon Fastener by Andrew Gomez

Pretty good replacement for Lundia open shelf pins. It's the right diameter and length, but the head is a bit too big (easier to pull out anyway). A hole is not necessary, but does not cause any problems. In the picture, this product is holding up a shelf compared to the branded pen shape above, and both are on the shelf too.
