About this item
  • 📦 Reliable Protection for Very Large Mail These white cardboard envelopes (350 × 285 mm) with a 50 mm self-adhesive flap provide strong, flat protection for very large documents, photos and printed materials. Each envelope weighs 66 g and helps prevent bending, tearing and damage during transit.
  • ⚡ Fast & Secure Peel and Seal Closure The 50 mm self-adhesive flap ensures quick and secure sealing without the need for tape or glue. Simply insert your contents, peel and seal for a clean, professional finish—ideal for offices and high-volume mailing.
  • ✉️ Rigid Yet Lightweight Construction Despite their extra-large B4+ size, these rigid cardboard envelopes remain lightweight at only 66 g, helping reduce postage costs while offering dependable protection compared to boxes or padded mailers.
  • 🌍 Eco-Friendly Recyclable Cardboard Made from recyclable cardboard, these envelopes provide a more environmentally responsible mailing solution without compromising on strength, durability or presentation.
  • 🛠️ Versatile for Business & Professional Use Ideal for sending large documents, posters, certificates, brochures, photos, magazines and printed materials. Suitable for personal use, offices, online sellers and professional shipping needs.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
