Gentle Warnings
Ink sensitivity: Fountain pen ink or delicate calligraphy may bleed if exposed to moisture. If the contents are precious, skip the freezer and try steaming instead (hold envelope 6 inches above a kettle’s steam for 20 seconds—never let it touch water).
No guarantees: This is a sometimes trick—not a always fix. It honors the envelope’s original design while offering a chance at redemption. Nothing more.
