You can make them yourself if you can find 4 hockey pucks.
Drill hole in center of pucks and install eye bolts that get put into the tie-down cut outs beneath the car.
These are not permanent. Put them in when you need them.
Probably a lot of videos on YT showing how to assemble.
Either or will work, but I'd personally opt for rubber simply for less chance of slippage. I bought a few hockey pucks and those have worked fine for a few years when needed. I found a rubber set on eBay that include the molded "frame lock" for about $20 that I'm going to buy to use with the Quickjack I just picked up. Even the rubber can be a tad slippery, so I intend to score mine with cross hatches just to be safe. I'm not quite as fearless as I used to be when getting under a car lol.
Something to consider regarding jack pads is their strength to resist shear as the car is jacked. When you jack one side of the car with a service jack, the geometry causes the jack point to move away from the jack and the jack must roll on its wheels to stay under the jack pad. If the resulting sideways force shears the jack pad, the car can fall, perhaps damaging panels and systems under the car.
I had a plastic jack pad shear a number of years ago, part of the pad spitting across the garage and the car falling which resulted in the need to replace a panel inside the front fender area.
From my perspective, strong aluminum jack pads and a service jack lifting cup or pad that will not let the jack pad slip away from the jack is essential. NO rubber or plastic jack pads for me.
