unenduring
Quick to fade
Not lasting or permanent; failing to persist through time.
Something unenduring fades, decays, or passes away rather than standing the test of time: Fame proved unenduring; within a decade no one remembered his name.
The word emphasizes impermanence, often with a note of disappointment or warning about things that seem solid but aren't.
