Review on ☕️ Charming Stackable Coffee Zocokey Novelty Ceramic: Brew the Perfect Cup of Joy by Jesus Gallagher

I bought these specifically for their compact stacking feature. The bottom edge they fit on is too small and as they are handmade the roundness of the hole will vary widely. I have a mug that is quite oval when opened. The combination of these two things makes for a VERY bad stack. Just today while reaching for the top cup, a VERY slight wiggle caused the nearby top cup to fall off and break. The fit is unreliable at best.
