Perfect for my stamp collection

These envelopes are exactly what I needed for storing and mailing my philately items. The 140g paper is thick enough to protect delicate stamps without bending.

Great quality, slightly pricey

The build quality is excellent and they look very professional for registered mail. I deducted one star only because they are a bit more expensive than standard office envelopes.

Excellent adhesive seal

The self-adhesive strip is strong and seals tightly every time. No need to lick anything, which is a huge plus for bulk mailing tasks.

Secure and sturdy

I use these for sending important legal documents via registered post. The thickness gives me peace of mind that the contents won't be damaged or seen through.

Good variety of sizes

Having options from size 3 to 8 in one order was very convenient. The No. 6 size fits my standard letters perfectly. Would buy again.

5 FAQ

Q: Are these envelopes suitable for international registered mail?

A: Yes, these envelopes meet the general weight and durability standards required for international registered mail services.

Q: Can I purchase individual sizes or only the mixed pack?

A: Currently, this specific model (DLZLC5B6) is sold as a mixed pack containing sizes 3, 5, 6, 7, and 8. Individual size packs may be available under different SKUs.

Q: Are these envelopes acid-free for long-term stamp storage?

A: Yes, the paper used is acid-free and archival safe, making these envelopes an excellent choice for long-term philately storage.
