### ⭐⭐⭐⭐⭐ Great tea/coffee cup
*by S***T on December 31, 2025*

Love this Cup! It’s a perfect size. I was really excited about it being leak proof so I turned it upside down and it instantly spilled BUT that was my fault. I didn’t realize the mouth piece has 2 clicks. One for just gently closing it to keep the heat in while drinking and one to actually lock it. One I figured that out 10/10. Keeps my tea hot and no bad taste. Color is so cute. Exactly like picture
