When she heard Xue Ya'er's words, Yao Zhi smiled and said, "Madam, to use this, you need to snap the little iron plate inside. It's like this."
With a snap, she clicked the small steel plate inside the gel. The next moment, the gel started to crystallize and warm up.
This time, not only Xue Ya'er, but even Lu Qianxuan and the servants were amazed by the gel warmer.
After the pad crystallized, Yao Zhi squeezed it to make it soften and said, "This hand warmer is hot after we snap the iron plate, so it's better to wrap it with a towel before using it."
Hearing this, Chun Hua used two handkerchiefs to wrap the gel warmer before she handed it to her mistress.
Holding the gel warmer, Xue Ya'er said, "It's really warm."
"This hand warmer can stay warm for 20 to 45 minutes. After the hand warmer cools down and becomes hard, it only needs to be soaked in boiling water for 5 to 10 minutes until the gel turns clear, then it can be used again."
