The cup is perfect with its details!
Color: Silver, Size: 6.8oz
It’s perfectly made, easy to clean and keep shiny. Does not spill at all when pouring to my tiny neck thermos.

Durable, Precise, and Perfect for Coffee on the Go!
Color: Black, Size: 3.4oz
I bought the Mongdio Espresso Measuring Cup as a Father’s Day gift because my husband is always brewing espresso to take with him—and this has become his new favorite tool.
Key Highlights:
Stainless Steel Durability: Unlike the thin glass cups we tried before (which shattered all too easily), this stainless steel model feels rock-solid and built to last.
100 ml / 3.4 oz Capacity: Perfectly sized for a double shot, ensuring you never overflow or waste a drop.
Double Spouts: Makes pouring directly into travel mugs or to-go tumblers a breeze—no drips, no mess.
Wooden Handle: Stays cool to the touch and adds a touch of style at the same time.
Sleek Black Finish: Looks great on any countertop and hides water spots or fingerprints.
Pros
Heavy-duty stainless steel construction
Accurate 100 ml measurement marks
Dual pouring spouts for precision
Cool-touch wooden handle
Cons
Handle can be a bit bulky in small drawers
Black finish may scratch over time if stacked
Final Verdict:
If you want a reliable, spill-free way to measure and pour espresso—especially for mugs on the go—this Mongdio cup is a no-brainer. It’s sturdy, precise, and looks great in any kitchen. Highly recommend!
