Grabber Hand Warmers are single-use, air-activated heat packs that deliver reliable, odorless warmth for hands and pockets for up to 7 hours.

These compact heat packs use a non-combustible blend of natural ingredients to generate comfortable warmth after exposure to air. Each shipment contains 80 individual warmers (40 pairs) sized 3.5 x 2 inches, designed to be slipped into gloves, mittens, or pockets. They activate in 15–30 minutes and reach an average temperature of about 135°F (57°C), with short peaks up to 156°F (69°C). Grabber emphasizes genuine-product purchases from authorized sellers to ensure quality and freshness.

How do Grabber Hand Warmers activate and how long until they heat?

Activation is simple: remove the sealed packet from its outer wrapper and expose it to air. No shaking is required; oxygen in the air reacts with the internal ingredients to start producing heat. Expect warmth to begin within 15–30 minutes and to continue for up to 7 hours under typical conditions.

• Activation time: 15–30 minutes from opening.
• Typical duration: up to 7 hours of warmth.
• Average operating temperature around 135°F (57°C); brief peaks to 156°F (69°C).
• Best used inside enclosed spaces like pockets or gloves for sustained heat.

What materials are inside the warmers and are they safe to use?

Each warmer contains a blend of iron, water, cellulose, vermiculite, activated carbon, and salt. The formula is non-toxic and non-combustible when used as directed; the reaction is a controlled oxidation of iron that produces heat without flame. These products are intended for external use only—do not puncture or open the inner packet.

• Key ingredients: iron, water, cellulose, vermiculite, activated carbon, salt.
• Non-toxic components; avoid ingesting contents or exposing to open flame.
• Dispose of used packets in household trash following local regulations.
• Store unused packs in a cool, shaded place to preserve freshness.

How should I use Grabber Hand Warmers for best results?

For optimal performance place the activated warmer inside a glove, mitten, or pocket so it retains air flow while staying close to the body. Use in an enclosed space to trap heat and prolong the warming effect. Avoid direct skin contact for extended periods—wrap with fabric if you need continuous contact to prevent discomfort from higher temperatures.

• Place inside gloves, mittens, or coat pockets for concentrated warmth.
• Avoid prolonged direct skin contact; use a fabric barrier if needed.
• One pair (two warmers) provides bilateral hand warmth; single warmers work for one hand or general pocket heat.
• Keep spare sealed packs in a cool area away from sunlight until needed.
