Keep your tools loaded, or play chemist and create your own custom brew.
Don't throw away a good empty. These refills are the most efficient way to keep your favorite mops and markers running on a full tank. Loaded with our signature handmade formula, this refill delivers the exact same aggressive, permanent bite you already trust.
Feeling experimental? We fully encourage it. These refills blend perfectly with any other ethanol-based ink or paint. Drop it into your current stash to boost its staining power, tweak the flow, or concoct a completely unique mixture from scratch.
