MHW-3BOMBER Pen Brush – slim as a pen, thorough at grinder and portafilter
You hold it like a pen, go once around the portafilter rim and through the grinder chute, and the loose grounds are gone. The matte black handle sits lightly in your hand and then slips into your apron pocket. The Pen Brush is one of the barista tools from MHW-3BOMBER.
The handle is made of aluminium alloy with a matte black finish (Matte Black), the bristles of PET. They loosen coffee grounds from portafilter, burrs and accessories without scratching the surfaces. At 155 mm long, the brush is handy and compact.
Pen Brush or wooden-handled brush?
Both do the same job, they just feel different. A wooden handle and natural bristles feel warm and classic. The Pen Brush with aluminium handle and synthetic bristles is the simple, easy-care option. In our experience, it copes well with a quick rinse under lukewarm water; then just let it dry.
Where you’ll use it
On the portafilter rim before locking in, in the dosing cup, in the grinder chute and on other espresso accessories. For thorough care of burrs and machine, you’ll find the right products in our machine and grinder cleaning range.

Who it’s made for
For everyone looking for a simple, sturdy tool at the coffee bar: for quickly cleaning the portafilter rim, dosing cup and grinder chute. And for baristas who like to keep their brush ready to hand in their apron pocket.
Tip from our café: In our experience, a clean grinder chute makes more difference than you’d think: otherwise, old grounds mix into the next dose and make the espresso flatter. Brush it through once, and Chestnut Delight shows its depth and warmth, Creamy Chestnut its note of roasted chestnuts. For espresso and filter alike, the omniroast Bright Cassis with its blackcurrant fruit is a good fit. You’ll find all varieties among our coffee beans. That’s our recommendation, one of many.
