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.

Almost blew up my microwave
Size: 20 Ounces, Size: 20 Ounces
TL;DR "A hilarious microwave mistake turned into a great home cafe upgrade. This 20oz cup is straightforward to handle, looks incredibly professional, and holds a level of heat that will literally burn you if you aren't careful." . Bought this for homemade coffee brewing, just to spice things up. But as I go ahead to heat up my new shiny stainless steel milk frother cup in the microwave, whoopdy doo. Ya can’t put stainless in the microwave! Regardless, it’s still a straightforward frother cup to handle, making it a great dollar investment for upgrading my home cafe setup. . 1. Spotless Stainless Steel: Its sleek appearance made me feel professional in the hands of an amateur like moi. Great quality! 2. Temperature Retention: I accidentally burnt myself because it stayed so hot, but that is a major positive. Proving the insulation works perfectly and keeps the milk piping hot. 3. Size: The 20oz capacity is accurate, providing the perfect amount of space for frothing without any overflow.
