I know people with a specific habit of buying really good stuff, high end tools, high end wine, clothes, bicycles, sports equipment, etc, but rarely using them. They'll spend tons of money on the good high quality stuff but will almost always use cheaper equipment, cheaper clothes, cheaper tools, etc, only bringing out the good stuff for special occasions, as though it's vital to them to always have the good stuff but not to use it lest they scuff it up or something.
Is there a term to describe this sort of habit? I've been looking for one for years and never found something that really resonates. Frugal seems close but doesn't quite get the part about buying the expensive stuff and not using it.
