To make professional detailed latte art, this is the perfect tool. While pure pouring technique will get you nice waves - from which you can shape hearts or flowers, if you want to add stems or arrows or printing or secondary (and tertiary) dollups, you'll need this pen.
Doing basic latte art is not hard to learn. And it makes a really professional impression on anyone - even on other baristas.
Fine-tipped Latte Art pen is 5.5" long.
