Common questions
What does #000 mean and what size items fit?
#000 is the industry standard designation for 4" x 8" mailers. This size accommodates items up to roughly 3" x 5" x 2", including small phones, sunglasses, cosmetics, jewelry boxes, and documents. The 3/16" bubble lining compresses slightly to fit varied product depths.
Is the peel-and-stick closure reliable for shipping?
Yes. The self-sealing strip creates a secure, tamper-evident closure that meets USPS, UPS, and FedEx standards. The adhesive is pressure-sensitive and sets permanently, no additional tape required unless extra security is needed.
How much does this mailer add to shipping weight?
Each mailer weighs approximately 0.14-0.16 oz empty, keeping dimensional weight minimal. At 4" x 8", this mailer qualifies for standard ground rates and often fits into USPS Priority Mail and UPS Ground pricing tiers for lightweight packages.
Are these mailers eco-friendly?
Yes. The exterior uses 100% recycled kraft paper and the polyethylene bubble lining is recyclable in many facilities. This supports sustainability goals while maintaining professional branding on customer-facing shipments.
