Thickness Guide
At 3 mil, these bags are classified as heavy-duty. Standard 1.5-2 mil bags work for lightweight items, but coins, metal findings, and hardware require the added protection of 3 mil construction. The extra thickness prevents punctures from sharp edges and provides a more substantial feel for retail presentation.
