May be biodegradable, but not water-soluble
Bought these for a wedding and was imagining them "disappearing" next time it rained, but if this was anywhere near grass, etc. it would stick around a while as I soaked some pieces in water overnight and they did not break down a bit. Ended up using wildflowers instead. Pretty little square confetti, but not what I was looking for.
