2.5″ CLASSIC ZINC GRINDER DISPLAY – 12-Pack

The 2.5″ Classic Zinc Grinder Display is a 12-pack of 5-piece herb grinders built for shops, crews, and heavy grinders who want consistent performance and solid margins. Each 2.5 inch (63.5mm) zinc grinder brings sharp teeth, kief catch, and a scoop so nothing goes to waste. If you need a countertop-ready set of grinders that can actually hang as daily drivers, this is it.

What You Get

• Ready-to-sell 12-pack — A full display of grinders in one grab, so you can stock the counter or hook up the whole friend group in a single move.
• Real kief collection — 5-piece design with a dedicated pollen chamber and included kief scoop so you can actually use what you collect instead of leaving it stuck in the corners.
• Solid daily-driver build — Zinc construction gives these grinders a reassuring weight and durability that stands up to being tossed in bags or passed around the circle.
• Comfortable 2.5″ size — Big enough to pack for the whole sesh, but still pocketable when you’re on the move.
• Color variety in every box — Bold, eye-catching finishes that make your display look alive and give customers options instead of a wall of the same exact grinder.
• Smoother prep, less mess — Multi-chamber layout keeps ground herb, kief, and unground material separated so your tray and table stay cleaner.

Best For

This 12-pack shines for small shops, convenience counters, and anyone stocking a booth or pop-up who wants a reliable mid-size grinder as an easy add-on. It’s also clutch if you’re setting up a house stash of tools for roommates, Airbnb hosts who cater to smokers, or sesh organizers who are tired of watching one lonely grinder do all the work while everyone waits.

If you’re building out a full smoking station, these grinders pair well with heat-proof dab pads and mats to keep your table protected from stray herb and sticky tools.

How to Use It

Each Classic Zinc Grinder breaks down into multiple layers: the magnetic lid with teeth, the grinding chamber, a storage layer, and a kief catch with a removable screen and scoop. Load your herbs between the teeth, reattach the lid, and twist until everything moves freely and you feel the material has broken down to your preferred consistency.

Ground material collects in the center chamber, while the finest particles fall through the screen into the bottom kief catcher. Over time, you’ll build up a layer of potent kief you can scoop out with the included tool and sprinkle where you want a little extra kick. For people who like to keep strains separated and organized, pairing these grinders with clear, heavy-bottom concentrate jars is an easy way to keep flavors and textures in check.

The zinc body gives each piece a sturdy, weighted feel when you twist, which helps keep everything tracking smoothly even when the grinder is full. Sharp, well-placed teeth do the heavy work, so you don’t have to over-crank or fight with sticky material every time you prep.

Specifications

Fit & Real-World Use

At 2.5 inches (63.5mm), this grinder hits the sweet spot between those tiny pocket grinders and huge at-home bricks. It’s easy to hold even if your hands are smaller, and there’s enough room inside to prep for multiple people without constant refills. The multi-piece design makes sense if you like saving kief or keeping your herb a bit more organized.

For shops, the color assortment and consistent sizing mean you get a clean, uniform display that still attracts attention. If you’re stocking a broader spread of gear, these grinders complement silicone and glass in any case alongside higher-margin glass jars and packaging for people who want the full setup.

Caring for Your Grinder

Over time, sticky material will build up on the teeth, threads, and screen — that’s normal. When everything starts to feel gunked up or harder to twist, it’s time for a quick reset. Disassemble the grinder, tap out any loose material, then soak the metal pieces in isopropyl alcohol for a short period, rinse with warm water, and dry fully before reassembly.

If you’re running a shop and doing demo pieces or heavy personal use, keeping a little cleaning kit handy with brushes and swabs (alongside your other storage and packaging supplies) makes it easy to keep these grinders looking fresh on the counter.

FAQ

Does this display really come with 12 grinders?

Yes. Each 2.5″ Classic Zinc Grinder Display includes twelve individual 5-piece grinders, ready to put straight into your case or on your countertop. They come assorted in bold colors so the display doesn’t look flat or boring.

What makes a 5-piece grinder different from a 3- or 4-piece?

A 5-piece grinder usually adds an extra chamber or more separation between the ground herb and kief compared to basic 3-piece designs. With this setup, you get a grinding section, a main catch chamber for your herb, and a kief catcher with a screen and scoop. That means you can keep your fluffy grind ready to go while still collecting the finest material separately for later.

How big is a 2.5″ grinder in real-life use?

2.5 inches (63.5mm) is a medium-to-large size in grinder terms. It’s wide enough to hold a decent amount of herb for group seshes, but still compact enough to toss in a bag or stash box without taking over the whole space. If you’re upgrading from one of those tiny travel grinders, this will feel like a big quality-of-life upgrade.

Will this grinder work well with sticky or dense herbs?

Yes. The zinc body and sharp internal teeth handle sticky, dense material better than cheap lightweight plastics. Just avoid over-packing; give the teeth a little room to move. If you’re processing especially sticky batches regularly, keeping your prep area on a nonstick non-stick PTFE sheet can help manage any fallout.

How do I keep the kief screen from clogging?

Eventually, any fine screen will start to clog up as oils and small particles stick to the mesh. When you notice kief isn’t falling through like it used to, gently tap the screen over a surface to shake loose material. For a deeper refresh, remove the section and give it a short soak in isopropyl alcohol, rinse, and let it dry completely before putting it back.

Is this more of a shop product, or is it worth it for personal use?

The “display” part mainly refers to the fact that it’s sold as a 12-pack — perfect for smoke shops and resellers. But it still works great for personal use if you’re buying in bulk for gifts, roommates, or backup gear. Some people like grabbing a display to match colors with different strains, rigs, or other smoke shop products in their setup.

What’s the best way to store this grinder when not in use?

Once it’s clean and dry, you can keep your grinder assembled with a bit of herb in the storage chamber if you like having something prepped and ready. Just don’t leave it somewhere extremely humid or wet. If you’re moving a lot of material or like to stay organized, pairing the grinder with labeled mylar bags makes it easy to keep different strains or blends separated and fresh.
