Thickness Guide
At 3 mil, these bags are classified as heavy-duty. Standard 1.5-2 mil bags work for lightweight items, but 3 mil provides the puncture resistance needed for jewelry with clasps, beads with sharp holes, or metal hardware. For extremely sharp or abrasive items, consider 4 mil or higher.
