Gemineye Grinders are made for grinding legal medicinal herbs that can be added to foods, vaporized or smoked. Our exclusive, coating process provides you with nano ceramic coated grinder that minimizes levels of friction, does not stick, and reduces the need for cleaning.

Gemineye Grinders are designed to be used with herbs cured at the industry standard 8-10% moisture level. Herbs above 12% moisture will cause resin to accumulate.

We have found that in ALL CASES where the grinder is sticking it's due to excess moisture content. Clean your grinder according to instructions for "Caring For Your Grinder". Additionally, leave your herbs out in a dry environment for 12-24 hours and grind to reduce moisture levels. 

If you're using any humidification devices or packs to maintain the proper relative humidity of your storage environment (recommended in very humid climates) ensure your levels are kept between 55% - 60% humidity.

If any part fails under under normal use within 1 year of purchase, contact us at gemini2investments@gmail.com and we will (at our discretion) send a replacement grinder to you at no charge.

Required information includes:

• Proof of purchase
• Complete delivery address
• Pictures showing the damage

Our replacement policy does not include cosmetic damage or parts that are dropped, scratched with a metal object or otherwise damaged from other than normal use.

With some light care, your Gemineye Grinder will last a lifetime.  Like all things that need to remain at peak performance, the occasional maintenance will be required. 

Cleaning the cutting area: While your grinder won’t generally need cleaning, if your herbs have an exceptionally high moisture content (12% or higher) or your medical needs necessitate a high volume, you may see some buildup. The ceramic makes it very easy to remove any material that does accumulate:

• Tap the grinder lightly on a solid surface each time you use it (we recommend doing this over a piece of paper so you can collect everything that comes out). This will prevent any buildup if done every time you use the grinder.

• Occasionally brush off the lips and teeth with an old toothbrush (to avoid any injury to your fingers from the sharp teeth). This will dislodge most of the particles that remain.

Cleaning the exterior: If any dirt builds up on the outside of your grinder, you can use a soft cloth with soap and water to wipe it away.

Lubrication: Your grinder is completed coated in our low-friction non-stick nano ceramic, and will not get stuck under normal use. However, if your herbs contain above 12% moisture, you may experience some slight buildup around the lips. This can generally be brushed right off using the techniques above, but if all else fails we recommend refined hemp seed oil (available online from Amazon). This will both lubricate your grinder and cause any buildup to be easily wiped away with a paper towel or rag.

Use of Solvents: Our ceramic is highly durable, and it’s safe to use rubbing alcohol or acetone on the coating without fear of damaging it.  Stronger chemicals could cause changes is color or brightness. We will not replace units that have experienced damage due to improper cleaning.

!!! NEVER USE METAL TO SCRAPE YOUR GRINDER !!!

With enough force it’s possible to dislodge the coating. While the coating is non-toxic and won’t burn, scratches will impede the function of your grinder. If you want to scrape the teeth to remove and save any of that potent residue, use the plastic pick provided at purchase.  These thicknesses offer the optimal combination of hardness and flexibility required to reach all the nooks and crannies.
