Send items with ease of mind
I’ve been using C5 cardboard envelopes for a few months now, and they’ve quickly become my go-to choice for mailing documents, photos, and small prints. The quality is outstanding — the cardboard is sturdy and gives a reassuring level of protection during transit. I’ve never had issues with bending or creasing, even when sending more delicate items.The size is just right for A5 documents or folded A4 sheets, making them super versatile for both personal and professional use. The self-seal adhesive strip is strong and secure, saving me time and hassle.Overall, these envelopes are reliable, professional-looking, and worth every penny. Highly recommended for anyone who wants peace of mind when sending important items

Do what they need to
What can you say they are standard sized envelopes with card back self adhesive strip and the do not bend text. They do the job at a decent price and are as durable and perform as well as any similar envelopes and are easily sealed……
