Notes on Meaning
- The term "cặp chì" is a compound noun where "cặp" implies a fastener or clamp that holds two things together, and "chì" is the material. It almost exclusively refers to a security or authentication seal made of lead. It does not mean a "pair" of lead objects.
- In modern contexts, seals are often made of plastic, but the term "cặp chì" may still be used generically for such security seals, especially in official or customs procedures.
