Espresso starter pack essential
Color: Silver, Size: 11.8 Ounces
I wanted something affordable to go with my entry-level espresso machine, and this milk frothing pitcher does the job perfectly. It works well, feels sturdy, and I don’t feel like I’m missing out on anything more expensive. Great value for the price! We’ve used it everyday since purchase and it’s super easy to clean.
