[Pro Tip📌] Just check these two things when choosing a tumbler! Criteria I learned after using over 20 tumblers 1️⃣ Capacity around 350ml Reducing bag weight comes first🎒 2️⃣ One-touch lid Twist-open types don't close properly, so it's a water-filled mess🌊 Straw cups are a cleaning nightmare🔥 I sent a pretty tumbler (the twist-open type) for the first day of school, and sure enough, all the workbooks came back soaked.🫠 Save this and make sure to check it before buying a tumbler🙌🏻 #ElementarySchoolMom #워킹맘살림 #텀블러추천 #신학기준비 #살림꿀팁 #콘수프기록집 #오늘의우리집
