Protect products and present your brand with custom mailers.
Custom printed FEFCO 0427 mailer boxes with double-walled protection for premium unboxing.
These FEFCO 0427 design printed mailer boxes provide secure, glue-free assembly and high structural integrity for direct-to-consumer shipments. Each box features double-thickness side panels when folded and a secure three-flap front locking mechanism to prevent opening during transit. They function as a protective shipping container and a clean branding canvas. Brands can print on the exterior, interior, or both to tell their story during the unboxing process.
Cubit supplies precise custom dimensions and multiple material bases to fit your products. Choosing our printed mailers helps you lower shipping costs by matching box dimensions to product sizes, which avoids carrier dimensional weight penalties. We provide direct access to technical support and digital dielines, helping you avoid production delays and get your packaging directly to your fulfillment lines on schedule.
