F.e.s.s. 70% RH Humidity Beads Crystals – Refillable & Reusable Humidity Beads for Storage Containers, Humidors, Instruments & Display Cases (32 Ounces)

F.e.s.s. 70% RH Humidity Beads Crystals are designed to help maintain a stable humidity level of approximately 70% in enclosed storage environments. When hydrated with distilled water, the dry crystals expand into humidity-regulating beads that gradually release moisture over time and shrink as moisture is dispersed. As a general guide, 2 tablespoons (1 ounce) of dry beads can yield up to 12 cups of hydrated crystals, allowing flexible use depending on container size. The beads are rechargeable and reusable, making them a long-lasting solution for humidity. Preparation is simple: slowly add distilled water, avoid over-saturation, and allow up to 12 hours for full hydration. Beads are not uniform in size or shape and naturally have a jagged crystal texture. Ideal for use in storage containers, cases, cabinets, display boxes, instrument cases, and other humidity-sensitive environments where consistent moisture balance is desired.

• Helps Maintain Approx. 70% Relative Humidity Designed to help stabilize enclosed environments at approximately 70% RH for controlled-humidity storage applications
• HIGH EXPANSION YIELD: Just 2 tablespoons (1 oz) of dry beads can hydrate to produce up to 12 cups of usable crystals for maximum coverage
• RECHARGEABLE & REUSABLE: Beads gradually release moisture over time and can be rehydrated with distilled water as needed for long-term use
• SIMPLE TO PREPARE: Slowly add distilled water and allow up to 12 hours for full hydration as crystals expand while absorbing moisture
• VERSATILE: Suitable for containers, cases, cabinets, display boxes, or other enclosed storage environments requiring humidity regulation
