Expandable Bottom Gusset Poly Bubble Mailers are designed for bulkier items that need more room than a standard flat mailer. The 4" bottom gusset expands to fit soft goods, apparel, accessories, and multi-item orders, while the 7/64" bubble lining helps cushion contents during shipping. Made with a durable white poly exterior, these mailers resist tearing, punctures, and moisture for a clean, professional shipping presentation.
