FAQ

What is the maximum weight these boxes can safely hold?

The boxes are rated with a breaking strength of 3 kilograms, meaning they can reliably support items up to that weight without risk of crushing. For heavier items, consider using a larger box size or additional internal cushioning.

Do I need any tools or adhesives to assemble the boxes?

No. The mailer boxes are designed to fold into shape in seconds using pre‑scored creases. Simply open the box, fold along the indicated lines, and the interlocking tabs will secure the structure without tape or glue.

Are the boxes suitable for international shipping?

Yes. The sturdy 32 ECT corrugated cardboard meets most carrier requirements for both domestic and international shipments. However, always verify specific carrier guidelines for weight and size limits before dispatch.

Can I customize the boxes with my own branding?

Rempry offers bulk ordering options that include custom printing services. Contact the seller to discuss logo placement, color variations, or other branding needs for larger volume orders.

How should I store the boxes to maintain their condition?

Store the boxes in a dry, cool environment away from direct sunlight or moisture. Keeping them flat and stacked loosely will prevent deformation and ensure they remain ready for immediate use.
