Bag it first Slide the sealed envelope into a resealable plastic bag. Why? Prevents condensation from dampening ink or warping paper when removed from cold.
Freeze gently Place in freezer for 60–90 minutes. Not overnight—prolonged cold invites moisture buildup.
Thaw with care Remove envelope (still in bag). Let sit at room temperature for 2–3 minutes until the exterior feels cold but no longer frosty. Never open while icy—condensation will smudge ink.
Peel with patience Start at one corner. Use your thumbnail or a butter knife to gently lift the flap. Work slowly, applying minimal pressure. If resistance appears, stop. Forcing it guarantees tears.
Accept the limits Some seals won’t release—and that’s okay. Better a intact envelope than a shredded one.
