Eirmai R10 Sealed Moisture-Proof Drying Box for DSLR Camera with Electronic Hygroscopic Card

Designed for DSLR storage and protection, the Eirmai R10 uses shock resistance engineering plastic integrated forming for a sturdy, one-piece body that resists breakage and provides long-lasting durability. A rubber sealing strip around the lid ensures complete airtight and waterproof performance. A balance air valve located above the box cover makes opening easier when the interior is tightly sealed — simply open the air valve so outside air can enter through the air hole to relieve the vacuum. The package includes an electronic hygroscopic card made from ABS flameresistant material; it is safe, energy-saving, free of odor pollution, damp-proof, mildew-proof, and reusable. The box contains an embedded thermometer so you can monitor internal humidity at a glance. A pointer reading in the 25-55% range indicates normal humidity; if the reading rises above 60%, add the moisture absorption card to lower humidity. Note: opening the moisture-proof box will let outside air in and temporarily raise humidity; once you close the box again, humidity will gradually decrease.
