Great question! The holder is designed to feel deliberately snug at first. This tightness is intentional and part of the precision-fit design. Over the first few uses, the holder naturally adapts to your specific grinder body, creating a custom grip that becomes smoother and more secure over time. Just apply firm, even pressure during the first few installations and it will loosen up perfectly.

The holder is 3D printed using a durable polymer that allows much tighter tolerances than traditional injection molding. The integrated sealing ring is made from food-grade silicone, so it is completely safe to use in contact with your grinder and brewing equipment. The silicone gasket also provides a secure, non-slip grip that holds everything in place without scratching your grinder body.

Absolutely, and that is one of the best reasons to own one! The holder turns your grinder into a single integrated unit with the cap and handle locked in place. No more loose parts rattling around in your bag or risk of losing small components on the go. The silicone seal prevents any migration during transport while still allowing quick removal when you are ready to brew at your destination.

Caring for your holder is simple. Just wipe it down with a dry or slightly damp cloth if it picks up any coffee dust or oils. Avoid exposing it to prolonged high heat, such as leaving it in direct sunlight inside a car. For the best fit retention over time, we recommend keeping the holder attached to your grinder when not in use. This helps maintain its custom-molded grip and ensures a consistent, snug fit every time.

Absolutely. Every espresso machine, grinder, and accessory is packed with the same precision we put into designing them. We use reinforced boxes and protective cushioning specifically tested for coffee equipment—because a damaged tamper or chipped machine housing isn't acceptable.

In the rare event your portafilter, grinder, or machine arrives damaged, our support team will sort it immediately with a replacement or full refund. No runaround.
