These are NOT Ivar pegs. The seller's description doesn't specifically mention Ivar pegs, but many questions/answers suggest these are replacement Ivar pegs. I could get them for half the price at Home Depot. These vortices are the wrong diameter for Ivar. In my screenshot I have an original Ivar pin (left), a newer Ivar pin (middle) and a pin from this seller (right). These pins are very narrow and easily fall out of the shelf hole when trying to insert the shelf. Big disappointment. I do not recommend this purchase to replace IVAR pins.
