I've partnered with Five Ounce Design to bring you a custom wooden cap that's beautifully crafted and tailored to fit our Wide Steel Hopper for the Zerno Z1 & Z2. It's designed to match the aesthetics and wood of your Zerno Z1 or Z2 and will fit over our bellows. Update: Remaining wooden Zerno caps are available while supplies last. Sold-out wood types will not be restocked. For future availability of wooden caps, please contact Five Ounce Design directly. Design Features: Fits over the hopper with or without the bellows inside May double as a dosing cup for small doses under ~20g Important Notes: This cap only fits the INTROVERT Wide Steel Hopper for the Zerno Z1 & Z2 and does not fit on the stock hopper for the Zerno Z1 nor Z2. The Wide Steel Hoppers and bellows are sold separately here All caps have unique grain and will look different from the ones pictured Due to the nature of wood, the shades or tones may not match exactly with your stock set. If exact shade matching is important for you, please contact Five Ounce Design! My Wide Steel Hopper for the Zerno Z1 & Z2 offers an easier dosing experience and is designed to perfectly fit our Silicone Bellows to help you clear out the retention and chaff inside the grinder and chute, reaching up to 0.0g retention.
