Great value / great look
Color: Silver, Size: 11.8 Ounces
Very nice stainless steel frothing pitcher but the Latte art pen is very small, much smaller than I expected. The size is perfect for working with one Latte at a time. All in all a nice product. No real complaints...I mean, what can go wrong with a frothing pitcher :)

Thumbs up for this product- order the next size up though!
Color: Silver, Size: 11.8 Ounces
I guess I was expecting a larger size. That’s on me. Oops! This is just like the larger one I have good quality, easy to clean, works well for my frothing for cold brew. I needed it to do one job and bammmm it does it!
