We run every lot through a 100% inspection before it leaves the floor—not a spot-check, but piece-by-piece, because a bad batch in your assembly line costs way more than our testing time. 2. The copper base is corrosion-resistant and free of nickel and lead, which we verify with a COA on each order, and the surfce treatments like epoxy coating or silk-screen hold up better than standerd plating for daily bag use. 3. Sizes run form 12mm up to 26mm, and we can tweak the shape or color to your Pantone spec, but the 16mm size is usually the sweet spot for most messenger bag straps. 4. If you need a sample first, lead time is 3-10 days, and we'll send it with teh same QC that bulk orders get—so what you test is what you'll get. 5. One thing that catches some buyers off guard: epoxy coating takes about 2 weeks to fully cure, so don't rush them into a humidity test right out of the box. 6. Anyway, bulk orders ship in 7-15 days, and our company can retest any flagged lot at no extra charge if you're not satisfied with the initial COA.

Sample orders with laser engraving take about 3-10 days, and bulk orders with your logo take 7-15 days after sample approval. We'll send you a digital proof first.
