The zipper is actually the main thing we get asked about most—it's the biggest limitation on these bags because a metal zipper on canvas can wear differently than a fabric drawstring, but what it does is give you real security for small items like keys or a wallet when you're out shopping or commuting.
We run a quick pull-test, basically checking the zipper teeth alignment against a 10-cycle open-and-close standard, and teh medium-soft canvas holds up better than stiffer materials for this—you won't get that crunchy feel you sometimes see with heavier cotton.

Custom colors are pretty much a given here, though we usually have stock in natural and black if you want to skip the 15-20 day production window, and printing tolerance is about plus or minus 2-3 ppm on batch consistency with a standdard COA form our in-house HPLC check.

The 100-piece MOQ is firm for custom Pantone or HTML matches, but we do offer a sample run for roughly $30 or so including shipping—just confirm lead time before you order, as sometimes the waterproff coating option adds 5 days or so to the turnaround.
20 days or so after confirmation is typical for production, and we keep a retest policy on hand if your batch comes up with a zipper issue or color shift beyond what's acceptable—better than reagent grade for most daily use cases, but it's not suited for heavy-duty industrial or chemical spill scenarios.
The MOQ is 100 pieces per design, but if you need less, we can sometimes work out a sample order first to test the market.
Yes, samples are available. Just let us know your preferred size and color, and we'll send a quote for the sample piece.
We apply a water-resistant coating on the canvas, so the bag can handle light rain or spills. It's not fully submersible, but it'll keep your stuff dry in a drizzle.
We use screen printing or heat transfer for logos, depending on the design. Yes, we can match any Pantone or HTML color you provide for both the bag and the print.
Absolutely. We can do custom packaging like poly bags, hang tags, or branded boxes. Just share your specs, and we'll include it in the production plan.
