100 x Security Seals – 25cm Pull‑Tight Numbered Plastic Tags (Yellow) Tamper Evident Quick Release Safety Seals for Fire Extinguishers, First Aid Kits, Roll Cages, Luggage & Compliance Use (UK)

These are decent enough security seals. They are very easy to use - thread the tail through the hole in the face of the tag, and that's it . The tags received do indeed all have unique numbers, and it's a six-figure number ( I assume other packs have different numbers); the numbers are clear and easy to read. The description says "quick release". I see no sign of a quick release option. You have to cut the tag to get it off, as far as I can see. I was able to break it with my hands, but it was quite strong. These will do the job, at least in low-risk setting. £12 for 100 seems reasonable value for money.
