✽ Set of 2 Easy breathing + anti-fog for glasses + reduced mask contamination With mask-wearing becoming mandatory these days, some common concerns include difficulty breathing, fogging of glasses, lipstick smudging, stuffiness, and skin irritation from masks. The "Ma-Fu-Ki" generates cool air inside the mask, preventing glasses from fogging up and preventing stuffiness caused by wearing a mask. It also creates more space between the mask and the face, preventing lipstick and makeup from smudging. Removing the pressure adjustment valve allows it to be used as a general mask guard, usable 365 days a year, not just in summer. (Ma-Fu-Ki is not recommended for use during exercise.) You can still feel a refreshing sensation even in general mode! Even with the pressure adjustment valve removed, the structure forms a barrier between the mask and the face, mitigating the reflection of hot breath onto the face and providing a refreshing feeling. ※ Please be sure to check the actual photos＾＾ Everything in the actual photos is included. ✨ Click here for #⊹Mac⊹'s product list ✨☜ ＿＿＿˖ ⊹ ˖＿＿＿˖ ⊹ ˖＿＿＿˖ ⊹ ˖＿＿＿˖ ⊹ ˖＿＿＿ ※ Because it has been taken out of the box for inspection, it is "Like New" even though it is unused. ※ Since it is new and unused, the operation has not been confirmed, so please purchase with your understanding. ※ There may be slight variations in size depending on the measurement method.
