## Questions & Answers

**Q: Does it stay flexible when frozen?**
A: Yes—our gel formula keeps the pack pliable right out of a –18 °C freezer, so it molds around joints, shoulders or jaw without hard spots. For extra softness, knead the pack for 5–10 s after freezing;

**Q: How many uses before it wears out?**
A: ≥300 hot/cold cycles under normal use; discard if swollen, lumpy or leaking. Dry the surface after each use and store flat—extends life ~30 %.

**Q: How long in the freezer?**
A: 2 h at –18 °C is cold enough; 4 h gives longer therapy.
