The interior cavity measures 8.375 inches wide by 10.5 inches long, with an outer envelope size of 8.5 inches wide by 12 inches long. A 5\/16-inch bubble lining cushions contents against impact during transit. The self-sealing closure strips on tamper-evident and secure without tape or heat equipment. At 330 mil total wall thickness, the mailer is lighter and more economical than corrugated cartons while still providing meaningful shock absorption. Licensed contractors, fulfillment staff, and shipping departments use these for outbound parcels where rigid cartons would add unnecessary cost and weight.\u003c\/p\u003e\n\u003cp\u003eThe B921 mailer is suited for shipping small electronics such as mobile phones, tablets, and accessories, as well as jewelry, watches, and similar items that need cushioning but not a full carton. The white exterior accepts labels cleanly. These are sold 50 units per pack, making them practical for both high-volume fulfillment operations and smaller-scale shipping needs. The poly shell resists moisture and minor surface abrasion, providing basic environmental protection during standard ground and parcel shipping.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch bubble lining provides twice the impact protection of unlined poly mailers\u003c\/li\u003e\n  \u003cli\u003eSelf-sealing strip closure  -  no tape, staples, or heat sealer required\u003c\/li\u003e\n  \u003cli\u003e330 mil total wall thickness for durable, puncture-resistant protection\u003c\/li\u003e\n  \u003cli\u003eLighter and more cost-effective than corrugated cartons for small parcel shipments\u003c\/li\u003e\n  \u003cli\u003eWhite exterior accepts shipping labels and direct printing cleanly\u003c\/li\u003e\n  \u003cli\u003e50 mailers per pack for efficient bulk use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for shipping small electronics, phones, jewelry, and similarly sized items with interior dimensions of 8.375 inches wide by 10.5 inches long.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo tools are required to use these mailers. Insert the item, remove the release liner from the self-sealing strip, and press the flap firmly to close. Do not overfill beyond the rated interior dimensions, as overstuffing compromises the seal and the bubble lining protection. Store unused mailers flat in a dry location away from direct heat sources to preserve the adhesive strip.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Width\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterior Width\u003c\/strong\u003e: 8.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterior Length\u003c\/strong\u003e: 10.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBubble Lining Thickness\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Wall Thickness\u003c\/strong\u003e: 330 mil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 3.45 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 19.5 inches x 17 inches x 12.25 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BOX PACKAGING INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B921\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOX PACKAGING INC","offers":[{"title":"Default Title","offer_id":68098887450930,"sku":"B921","price":133.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b25937b5f3de1313e25dbce9aa07859.jpg?v=1793281721","url":"https:\/\/voomisupply.com\/products\/box-packaging-inc-b921-bubble-lined-poly-mailers-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
