A little bit of tender loving care goes a long way.
Generally, the best viewing period for preserved flowers is 6 to 12 months.
To keep your flowers looking bright and beautiful as the day your purchased it, keep it away from humid or wet environment (like your bathroom!).
When preserved flowers come in contact with water, it will absorb the moisture and cause the flowers to look translucent, or have slight damp spots.
If you have accidentally wet your flowers, do not panic! Just leave it to dry, overnight in an air-conditioned room and it will return back to it’s beautiful self the next day.
If you own a dehumidifier, that would also help with returning your preserved flowers back to its original, dry state.
