KIRIBAI Waist Thermal Warmer 5pcs is a 'targeted, long-lasting self-heating product' designed for waist warmth and comfort, using Japan��s mature self-heating technology. Its core features are:
- Targeted Waist Design: The warmer has a curved, ergonomic shape that fits the natural contour of the waist��unlike regular rectangular warmers, it adheres closely to the waist without shifting during movement (e.g., walking, sitting), ensuring warmth is focused on the waist.
- Safe & Long-Lasting Heat: Adopts a multi-layer heat-generating formula (iron powder, activated carbon, vermiculite, salt)��it activates quickly (heats up within 10 minutes) and maintains a stable temperature of 40-55�� for 8-12 hours. The outer layer uses heat-insulating material to prevent direct contact with skin (avoiding burns) and lock in warmth.
- Easy to Use & Clean: Each warmer is individually packaged (ensuring freshness and preventing premature activation). It has a self-adhesive backing��peel off the protective film and stick it to the inside of clothing (not directly on skin) for immediate use, with no residue left on clothing after removal.
- 5-Piece Value Pack: Contains 5 individually sealed warmers��suitable for daily use (e.g., 1 piece per day) or emergency backup, with compact packaging that��s easy to store at home or carry in a bag.
- Wide Temperature Adaptability: Works effectively in temperatures as low as -10�� to 20�桪suitable for both indoor (air-conditioned rooms) and outdoor (cold weather commuting) scenarios, meeting diverse warmth needs.
