Q: can u put one of those small locks on the zippers? i want to keep people from opening it while at work.

Bought it as a gift. I have never used one.

Q: It has a beautiful design, is this lunch bag leak-proof?

Double-layer lunch bag, the lower compartment is leak-proof, and the upper insulation is better.

Q: Does this lunch bag have a shoulder strap?

The insulated lunch bag comes with an adjustable and removable shoulder strap.

Q: How does the strap turn it into a backpack? (It has backpack rings)

Thank you for your question, please take out the shoulder strap inside the double insulation lunch bag, adjust it to the most suitable length (very important), fold it in half and pass it through the ring buckle, then pass the two ends of the shoulder strap through the fold to finish, dear, you can refer to the video below.
