"Dude, That's Genius!"

Prepare for awe and envy. Your friends will want one immediately.

FDA Compliance (Raw Material): The virgin PETG filament used in GRYNSERT production complies with FDA (Food and Drug Administration) regulations for food contact. This means the raw material itself is considered safe for applications involving food and beverages.

What is GRYNSERT?

It's a two-piece premium grinder engineered to seamlessly fit inside any standard ZYN can, transforming it into a discreet, all-in-one accessory.

How does GRYNSERT attach to the ZYN can?

The two components simply snap into place, replacing the original inserts inside the lid and the base of the ZYN can. No adhesives or modifications are required.

How well does it actually grind?

Despite its compact size, GRYNSERT uses a precision-engineered tooth pattern to deliver a consistent, fluffy grind quality, optimized for the amount you would typically use.
