Frequently Asked Questions
For initial heating, microwave for 1–2 minutes, depending on your microwave wattage and the weight of your product:
• 2.5 lb heat wrap: 1 minute 40 seconds (maximum 2 minutes)
• 4 lb heat wrap: 2 minutes 30 seconds (maximum 3 minutes)
We use fresh seeds, and the natural moisture inside may cause the product to take longer to heat during first use.
Always check the temperature before use and adjust heating time as needed.
After about 20–30 minutes, it’s normal for the heat wrap to feel cooler on the surface. However, the inside remains warmer than room temperature, which means it requires less time to warm up again and continues to provide comforting heat.
To prevent burns to the product, properly fold the product and flip it can ensure the even heating. The seeds are very hot inside, from the outside, it is hard to feel it. When using it, the heat will build up.
The wrap stays warm for approximately 20–30 minutes. To help retain heat longer, we recommend covering the wrap with a blanket or towel while in use.
Heat therapy works well. Due to the nature of the natural seeds, they don't get very cold compared to the chemical pads.
