Pick the case by the number on the side of it

SHOWKOO builds hard and soft cases in four sizes, and every page here starts with the measurement that decides the purchase. You get the shell size in inches, what the set nests into, the weight when the maker states it, and what each piece is built from.

Every number above comes from the carrier's own baggage page, read on 12 September 2026. Two of the three count wheels and handles inside the limit, and that is how a case sold as a 22-inch carry-on still gets turned back at the gate.

Carry-on at 20 inches, checked shells at 24 and 28. These ship as a case with a weekender duffel and a toiletry bag, and only the checked sizes expand.

The SHOWKOO story

Twenty-eight inches of learning

We at SHOWKOO started in 2018, and the thing that started us was friction. Not the poetic kind: the wheel that drags on carpet, the handle that wobbles at full extension, the shell that looks right in a photograph and splits at a corner when the belt gets busy. Our first case was a 24-inch hard shell we carried ourselves, and we rebuilt it three times in a year. Everything in this range descends from that one.

That history explains two habits. The first is bracing. Under the top carry handle and the side handle sit two reinforcement brackets, because a hard shell cracks where a person lifts a loaded case with one arm. The second habit is stranger for a luggage brand: we sell the telescoping handle on its own, in 2 lengths, so a case with a dead handle gets a new one instead of a spot in a landfill.

Four shells, drawn to scale

16″4 pieces
20″36 pieces

Drawn to scale from the shell sizes in this catalogue. A set counts once in every size it contains.

The SHOWKOO lineup now covers 19 lines and 68 separate items. Nested sets carry the bulk of it, 41 of them, because a 20-inch case inside a 24 inside a 28 ships in one box and stores in one closet corner. Around those sit single carry-ons, wide checked shells that expand by a fifth, canvas duffles, a 40-litre laptop backpack and quilted totes for the seat in front of you.

The shells are the part people ask about first. Our hard cases use 100% polycarbonate instead of the cheaper ABS blend. Polycarbonate flexes under a baggage belt and comes back to shape, and it takes a textured finish that hides the scuffs every checked bag collects. Soft cases use high density oxford, which gives up some impact protection and buys back outside pockets and a little give when you overpack.

Wheels and locks follow the same plain logic. Every rolling piece runs double row spinner wheels that turn through 360 degrees, and every case closes on a YKK zipper with a TSA lock built into the top. SHOWKOO makers publish drop and walking tests for the hard lines, with numbers we quote as their claim and not as a standard: 20 kilograms loaded, 40 kilometres walked, 10 kilometres an hour.

Soft goods

What rides on top

Duffles, backpacks and totes, measured in litres, not in adjectives.

All travel bags

What we will not do is pretend the sizes are interchangeable. A 20-inch shell fits the cabin rule that most American carriers publish, and it does not expand. A 24-inch shell expands by twenty percent, and on most carriers it flies in the hold. A 28-inch shell is a checked case in every sense, and a full one is heavy enough that airline weight limits matter more than the luggage does.

Colour is the one place where we let ourselves have fun. The hard shells come in the flat blacks and greys that hide a scuffed corner, and also in magenta, sea blue, champagne and pale green, because a bright shell is the fastest thing to spot on a carousel at midnight. The G-Series adds a tan trim across the corners and the grips, and that trim is the detail people recognise across a terminal.

Who buys what follows a pattern we can see in the ratings. Families and anyone moving house take the five piece sets. People who fly for work every month take a single 20-inch shell and then come back for a 28 when a holiday needs it. Students take the 40-litre backpack, which lies flat for the scanner and swallows a 17-inch machine. The spare handles go to people who already own a SHOWKOO case and want a second decade out of it.

Prices, colours and stock move on the retail side. The sizes, the materials, the fittings and the ratings buyers have left stay put, and those are what each product page gives you. Check the rest at checkout before you pay.

Spare parts

The part that usually breaks first

A new telescoping handle costs a fraction of a new case, and fitting one takes a screwdriver.
