Why this gift works
The Master Lock 4688D TSA Luggage Lock is a small combination padlock with a flexible braided steel cable shackle that fits suitcase zipper pulls. It has a set-your-own 3-digit combination, and TSA screeners can open and relock it without damage; Master Lock says it is recognized as a TSA-approved lock in 29 countries. The body is 1-3/16 inches wide. This listing is black.
A lock on the zippers keeps a checked bag from falling open and deters casual tampering, and a TSA-compatible lock will not be cut off at security. It is an inexpensive add-on for anyone who checks bags.
Who is this gift for?
Great for
- Anyone who checks bags
- Pairing with a luggage tracker
- A family on a big trip
Think twice if
- They want high security
- They only travel carry-on
The catch
A 3-digit combination allows only 1,000 codes, and the thin cable shackle is a deterrent rather than high security.
Skip if they travel carry-on only, or already lock their bags.
