Is ABS hard-shell luggage durable enough for checked bags?

ABS is the entry-level hard-shell plastic. It handles normal travel and light rain well but is more prone to cracking than polycarbonate or aluminum under heavy impact. It suits occasional travelers better than frequent flyers.

Do all five cases have TSA locks and spinner wheels?

The listing shows a TSA lock and four wheels on the set. Confirm per size before buying, since smaller nested cases in budget sets sometimes skip the lock.

How do the five sizes nest?

The cases nest inside the largest one for storage, so the set takes roughly the space of the biggest case. Check the listed dimensions to see which sizes fit carry-on limits.

How does this compare with a polycarbonate set?

Polycarbonate flexes and springs back from impacts, so it usually lasts longer than ABS. This set counters with five sizes and a printed finish at a lower build tier.

Can the smallest case be used as a carry-on?

Check the dimensions against your airline's carry-on limit before relying on it. Nested sets often include a small case that fits under the seat rather than overhead.
