Human Grade Storage Grinder 1A – 2.5″

The Human Grade Storage Grinder 1A includes a dedicated storage chamber built into the grinder’s 4-piece design, separate from the grinding components. This chamber is made from clear plastic with a viewing window so you can see the contents at a glance, and it keeps your ground flower secure and ready for use without needing a separate container. The storage chamber sits between the aluminum grinding section and the pollen collection chamber, making the grinder a complete all-in-one herb preparation and storage solution.

The Human Grade Storage Grinder 1A measures 2.5 inches, or 63mm, in diameter. This is the standard 2.5-inch size found across much of the Human Grade grinder range, providing enough loading capacity for most daily grinding sessions while remaining compact enough to carry in a jacket pocket or small bag. The 2.5-inch footprint is comfortable to hold and twist, and the grinder can stand upright on a flat surface without tipping.

The Human Grade Storage Grinder 1A uses a combination of materials across its four pieces: the top lid and grinding chamber are made from aluminum, while the storage compartment and pollen collection base are made from clear plastic. The aluminum sections provide the structural strength for grinding, while the clear plastic storage sections allow you to visually check how much ground herb you have stored without disassembling the grinder. The integrated pollen screen is built into the plastic storage section.

Yes, the Human Grade Storage Grinder 1A includes an integrated pollen screen that separates fine kief particles from the ground herb and collects them in the bottom chamber. The clear plastic construction of the collection section allows you to see how much kief has accumulated. The included scraping tool makes it easy to retrieve the kief from the bottom chamber when you are ready to use it. This kief collection feature is in addition to the grinder’s built-in herb storage capability.

The Human Grade Storage Grinder 1A differs from the standard Human Grade Grinder 1A primarily in that it includes a dedicated built-in storage chamber as one of its four pieces. The standard 1A is an all-aluminum 4-piece grinder with an upper chamber, grinding chamber, pollen screen, and bottom kief collection chamber. The Storage Grinder 1A replaces part of this structure with a clear plastic storage compartment that can hold ground herb separately from the kief collection chamber, giving you an additional dedicated space to store prepared flower.

Yes, the Human Grade Storage Grinder 1A is a practical travel grinder because its built-in storage chamber eliminates the need to carry a separate herb container. You can grind your herb, transfer it to the internal storage chamber, and carry everything in one compact 2.5-inch unit. The clear plastic sections let you see how much herb and kief you have at a glance, and the aluminum grinding components are durable enough to handle the bumps and knocks of regular travel without issue.
