Go for Vanadium oxide instead of platinum, better for your wallet

"Iron oxide" is even cheaper.
As for the eBay item, NurdRage and more than one active member here have been ripped off by fake "platinum" products from eBay.

Wow those are cheap. If they do contain platinum as you suggest it will not be very much. Wiki suggested they contain platinum but I could not find
any dissection info on them to confirm that.
Years ago you could get a glow wire type gas stove lighter It used a large drycell to heat a small platinum (allegedly) filament to a barely
perceptible dull red heat. When placed in the gas stream it would glow brightly and then ignite the gas. I keep an eye out looking for a discarded one
in charity shops and recyclers.
They also make a butane powered curling tongs that use a catalyst. Possible this is one https://www.amazon.co.uk/BaByliss-2585U-Large-Cordless-Style...
They use a battery powered filament to initially heat up the catalyst. Perhaps they have little platinum in them too.

You could buy these:

The disc at the bottom is a piece of moulded plastic with a platinum powder on it. Again, I don't know how much platinum there is but there is at
least some.
