My must-have in my travelling kit, in my bag, for staycation and for my kids everyday IFC/CC. Prefer to buy in bulk like 5/10 sets and this is good price. Cheapest thus far. Other sellers sell at $4++ per box and have MOQ of 5 boxes per order bill. Click the link here to purchase https://s.shopee.sg/3q1SSHXOlv #happynoz #cough #antivirus #flu #antibac #detox
