Dip 1/3 to 1/2 the beads in distilled or reverse-osmosis water (horizontally so the bead case is upright like featured in the picture). The reason why we do not recommend using tap water or certain types of bottled water is because the minerals in the water will discolor the beads.
Shake off excess water and wipe it dry. You'll notice the dry, unsaturated side of the beads will begin to absorb the water from the saturated side. This is normal, so do not fully saturate the dry-side.
Place into your humidor and begin using. The VaporBeads will wick off moisture to the correct ratio until it drops to equilibrium at 50% RH. You can rehydrate the VaporBeads from step 1 once every 2-3 weeks, but do not constantly saturate or consistently keep wet as this can cause mold growth. With the VaporBeads, less is more!
