How to choose a hard-shell suitcase set with TSA lock: compare sizes, materials and wheels

A hard-shell suitcase set with TSA lock may seem like a straightforward purchase at first glance. However, suitcases can vary considerably in size, weight, layout and ease of use. A set with four sizes can be useful for a family or for travellers who take different types of trips, but only if the suitcases also comply with your airline’s baggage rules.

Pay particular attention to these three common pitfalls:

• Hand luggage that exceeds the current size limits. Measurements including wheels and handles often count. Always check your airline’s rules.
• A lightweight ABS suitcase whose own weight is not considered carefully enough. A larger suitcase offers more capacity, but its size and contents can still make it heavy very quickly.
• Treating a TSA lock as complete security. The lock is designed to keep the suitcase closed during transport. It does not prevent a suitcase from being opened or damaged. During an inspection, authorised staff may use a suitable access system, depending on the type of lock.

Which specifications are important?

1. Material and empty weight

ABS is a widely used plastic for hard suitcase shells. The material can offer a practical balance between weight and protection against normal knocks during transport. However, information about scratch resistance, drop tests or durability comes from the brand or seller. According to KONO’s product description, the suitcases have been checked for factors including drops, handle load, rolling and zips; this is a claim made by the seller and not an independent test assessment.

In addition to the material, always check the empty weight. According to the product specifications, the KONO suitcases in this set weigh:

• Beauty case: 0.72 kg
• 20-inch cabin suitcase: 2.62 kg
• Medium 24-inch suitcase: 3.18 kg
• Large 28-inch suitcase: 4.0 kg

A lightweight suitcase can therefore leave you with more room within a baggage allowance, but you should also check the maximum permitted weight for your flight.

2. Size and capacity

A 4-piece suitcase set is particularly practical when you alternate between weekend trips, business travel, family holidays and longer journeys. The KONO set mentioned includes several sizes:

| Component | External dimensions | Stated capacity | Intended use according to the product information | |---|---:|---:|---| | Beauty case | 31 × 25 × 18 cm | approximately 11 litres | Cosmetics and toiletries | | Cabin suitcase | 57 × 38 × 24 cm | approximately 40 litres | Trips of approximately 3–5 days | | Medium suitcase | 67 × 44 × 27 cm | approximately 65 litres | Trips of approximately 5–7 days | | Large suitcase | 76 × 50 × 31 cm | approximately 100 litres | Longer holidays and family trips |

The dimensions are external and include the wheels and handles. According to the product information, the internal dimensions may differ by approximately 1 to 2 cm. A cabin suitcase or hand-luggage suitcase may comply with many airlines’ requirements, but this is not automatically guaranteed. Before you travel, check the current size and weight restrictions.

3. Wheels, handle and layout

Four 360° spinner wheels can make it easier to manoeuvre through stations, airports and hotel floors. Also consider the construction of the telescopic handle. According to the product specifications, the KONO set has an aluminium handle with three positions.

Inside, a zipped divider, mesh pocket and adjustable packing straps are useful for keeping clothes and smaller items in place. A beauty case with a trolley strap can be attached to the suitcase. This is especially useful when walking through an airport and you want to keep your hands free.

How to use a TSA combination lock

KONO’s product information states that the locks are preset to 000. To change the combination:

1. Press the reset button with a pen or toothpick.
2. Set the three digits to your chosen combination.
3. Release the reset button and check that the new code works.

Do this before packing your suitcase. Do not write the code on a visible note attached to the handle. A TSA lock is not a substitute for handling valuable belongings with care.

Frequently asked questions

Will a 20-inch cabin suitcase fit every airline’s requirements?

No. According to the product information, the KONO suitcase measures 57 × 38 × 24 cm, including wheels and handles. This may fall within the permitted cabin dimensions for many airlines, but the rules vary by ticket, airline and fare. Always check the current baggage conditions.

How long does an ABS suitcase last?

Its lifespan depends on use, how heavily it is packed, the surface it is used on, the zips and how the suitcase is handled during transport. Before buying, check the wheels, seams, handles and closure. Avoid overpacking and do not drag the suitcase over rough surfaces for extended periods. According to KONO’s own product information, quality checks have been carried out, but this does not guarantee a specific lifespan.

Are four suitcases cheaper than buying them separately?

That depends on how often you use the different sizes. A suitcase set with a beauty case can be practical for families and travellers taking a variety of trips. If you usually travel with hand luggage only, you may mainly use the smallest suitcase. Compare the total price with your expected usage and check that you have enough storage space at home. The nesting design of this set can help you store the suitcases compactly.
