A 4-piece luggage set may seem appealing because you get several sizes in a single purchase. However, not every set is equally practical. A suitcase may be lightweight on paper, but wheels, handles and a lock can add considerable weight. A cabin suitcase also does not automatically comply with every airline’s baggage rules.
Pay particular attention to these three common pitfalls:
Looking only at the size label
An “20 inch” cabin suitcase may be larger than expected once the wheels and handle are included. Airlines set their own maximum dimensions and weight limits.
Mistaking ABS for indestructibility
An ABS luggage set is generally lightweight and has a hard exterior, but material strength also depends on wall thickness, construction and use. No hard suitcase is completely immune to scratches or damage during baggage handling.
Treating a TSA lock as complete theft protection
A luggage set with a TSA lock allows airport staff to inspect it without forcing the lock in the same way. However, the lock does not prevent a suitcase from being opened if someone can access the zip or another fastening.
Always compare the external dimensions, including wheels and handles. The KONO set is listed with the following sizes:
The capacity figures are useful when planning clothes, shoes and toiletries. Internal dimensions may differ from the external measurements. For this reason, check your airline’s current rules before departure, even if the product information states that a particular size is accepted as hand luggage by several airlines.
A hard-shell luggage set protects its contents with a rigid outer shell. ABS stands for acrylonitrile butadiene styrene, a plastic often used for lightweight suitcases. Its advantages include a relatively low empty weight and a smooth surface that is easy to clean with a damp cloth.
Also pay attention to:
According to KONO’s product information, the suitcases feature adjustable criss-cross packing straps, a zipped divider and a mesh pocket. These are verifiable organisational features, but they do not automatically indicate how long a suitcase will last with intensive use.
A wheeled luggage set is only comfortable to use when the wheels turn smoothly and the handle feels stable. Spinner suitcases usually have four wheels that can rotate in multiple directions. This can be convenient at stations, on airport floors and in hotel corridors, as you can push the suitcase alongside you.
According to the product description, the KONO models feature four 360° wheels, a double-wheel design and an aluminium handle with three positions. When your luggage arrives, check that all the wheels turn evenly and that the handle extends without excessive play.

Why it suits this profile: This spacious wheeled bag is designed for camping, fishing and trips where flexible packing space matters more than a hard shell or cabin size.
The 110-litre capacity, packed size and approximate weight of 1.75 kg are clearly stated. This lets you assess the bag by its loading capacity rather than by general marketing claims.
Foldable design, 110-litre capacity, built-in wheels and a stated packed size of 42 × 21 cm.
Choose a 4-piece luggage set if you regularly switch between short and long trips, or if several members of your family need different sizes. A set with a cabin suitcase, medium suitcase, large travel suitcase and beauty case offers more flexibility than a single model.
When comparing sets, consider the following:

That depends on the dimensions, weight and rules of your airline. Use the smallest suitcase as cabin luggage when its external dimensions fall within the permitted limits. A 20-inch model is not automatically accepted by every airline.
Its lifespan depends on use, how heavily it is packed, transport and maintenance. ABS is lightweight and suitable for many travel situations, but check the zips, wheels and handles regularly. Avoid overloading the luggage and clean the wheels if sand or dirt gets caught in them.
That depends on the offer and how you plan to use it. A set can be practical when you need several sizes. If you only need a cabin suitcase, buying a single model may be more efficient. Compare the total price with the sizes and features you will actually use.
