I’m really impressed with these 4oz espresso cups. The bright silver finish looks premium, and the wooden handle feels sturdy and comfortable to hold—no worries about heat transfer. The double spouts make it super easy to pour shots cleanly into two cups or split a double shot without mess. The size is perfect for single or double shots, and it doubles nicely as a small measuring cup for my coffee bar setup. It feels durable and well-made, and it definitely adds a bit of flair to my espresso routine. Overall, great quality for the price. Highly recommend for home baristas!

Handle Came Off

Excellent for pulling espresso shots, looked great, no rusting... until the welded handle just popped off after a few months with hand washing only.

Nice item, looks a bit bigger on the web site but the size works for me fine. Looks to be of good quality as well. Pours well, ergonomically good to hold and use/. Good price as well
