Review on 🔩 Premium Nickel Plated Shelf Pins Kit - 120Pcs, 4 Styles - High-Quality Shelf Supports for Cabinets, Entertainment Centers, and Furniture Shelf Holes by Tyrone Lyons

Since all 5mm pins are only 4.7mm thick when measured with a micrometer, they hang in around the 5mm holes so you run the risk of elongating holes and failing at some point in the future. This seems to be typical of all online brands I've tried - none of them are advertised the way they are advertised, which basically means rubbish. But it's still possible that you can find holes that the pins fit in. You just can't predict based on consistently inaccurate product descriptions. So feel free to send this junk back to the sellers who don't care.
