Description
The household this SHOWKOO set is for
This is a three piece hardside set at 20, 24 and 28 inches in a polycarbonate and ABS blend, finished in mint green, with a side mounted TSA lock and expansion on the two larger cases. The buyer it fits is a family or a couple who fly a few times a year and want matching pieces covering every size in one purchase. The 20 inch is the cabin candidate, the 24 inch is the one person for a week bag, and the 28 inch is the checked bag for long trips.
With more than twenty seven thousand ratings, this is one of the most bought luggage sets on the market, and that alone tells you something useful: the design has been through enough hands that its failure modes would be well known by now. It is worth noting that the item model number recorded on this listing is the literal string Valise set rather than a model code, and no manufacturer name is recorded at all, which is the sort of gap that makes chasing a warranty harder later.
Dimensions, and the one figure published
The specification table gives 29.92 by 21.26 by 12.2 inches. Nothing states which piece that describes, and nothing states whether wheels and handles are included. Given the numbers it is either the 28 inch case measured with wheels or the carton the nested set ships in, and those two are close to each other by design, since sets of this kind pack the smaller cases inside the largest one.
If that is the 28 inch case, it is over the usual limit
Most airlines cap a checked bag at around 62 linear inches, meaning length plus width plus depth added together. The published figure totals 63.4 linear inches. If it describes the 28 inch case, that bag exceeds the common cap before the expansion is used, and the maker states the 24 and 28 inch cases expand by 20 percent, which would push it further. If the figure describes the shipping carton instead, then the 28 inch case is smaller than that and may well be inside the limit, but the listing gives no way to tell. Measure the largest case on arrival and check your carrier’s linear limit and oversize fee before you fly with it.
No dimensions at all are published for the 24 inch or the 20 inch pieces. The 20 inch is the piece a buyer intends to carry on, and it has no published measurement of any kind. The maker says only that the 20 inch is best for carry-on. That is the maker’s framing and we will not restate it as compliance: the commonly quoted United States domestic cabin allowance is near 22 by 14 by 9 inches with wheels counted, budget and regional carriers publish tighter figures, and many international carriers add a cabin weight cap. Ask the seller for the 20 inch case’s exterior dimensions with wheels included.
Shell, wheels, handle and lock
The shell is named as an extra thick polycarbonate and ABS blend with a textured finish. Naming the blend is a useful disclosure, and the honest reading is that a PC and ABS mix behaves between its components: better than plain ABS at absorbing an impact and returning to shape, not as good as pure polycarbonate. Extra thick is a marketing phrase with no number behind it. The textured finish is a genuine benefit, since it hides the fine scuffing a gloss shell shows within a trip.
Two construction details on this listing are unusually specific and worth crediting. The maker describes soft TPU wheels with lubricating balls in the bearings, which is a real specification rather than a slogan: TPU is quieter and grips better than hard nylon, and a lubricated bearing is what keeps a caster rolling once grit gets into it. And it describes two reinforcement brackets added on the underside of the top and side carry handles specifically to stop the hardshell cracking at the handle mounts. That is the exact failure point on hardside luggage, where a shell tears around a lifting handle, and addressing it directly suggests someone looked at returns. The maker also refers to drop testing and to a walking test with a 15 kilogram load. Those are the maker’s own tests, described in the maker’s own words, and we report them as claims rather than as verification.
The handle is a three step aluminum telescoping tube. The lock is a side mounted TSA recognized type, which opens to a universal master key held by screeners: a deterrent against casual opening, not security for valuables. Inside there is a full zip divider with organizational pockets, cross straps and a small pouch in the shell for small items.
Capacity, weight and what the numbers cover
Capacity is published as 93 liters in both fields, and a feature bullet begins to break it down as 38 liters for the 20 inch and 60 for the 24 inch before the text is cut off. Those two alone total 98, which already exceeds the 93 liter headline figure, so the 93 is not a set total. It is most likely the 28 inch case alone, possibly expanded. The listing does not say. What you can take from the fragment is that the 20 inch holds about 38 liters, which is a normal and reasonable cabin volume, and that the 24 inch holds about 60.
The weight is 26.4 pounds, restated as 12 kilograms, which is consistent and is clearly the combined weight of all three nested cases rather than any one of them. No per piece weight is published, which is the figure you actually need, since the empty weight of the 28 inch is what eats your checked allowance and the empty weight of the 20 inch is what eats your cabin allowance. Split proportionally across a 20, 24 and 28 inch set, 26.4 pounds would put the cabin case near seven pounds and the large case near eleven, but that is our arithmetic and not the maker’s data. Ask.
Warranty, standing and the alternatives
No warranty term appears anywhere in the source data. No length, no coverage description, no exclusion list. Combined with the missing manufacturer name and the placeholder model number, that leaves a buyer with no clear route to a claim. On a three piece set the useful question is whether a single failed case can be replaced, and nothing here answers it. Ask before ordering, and ask specifically about damage caused by airline handling, which is the damage checked bags actually suffer.
The listing shows 4.4 stars from 27,595 ratings and positions of fifth in the suitcases chart and sixth in luggage sets. That is one of the largest review bases in the whole catalog and a strong pair of chart positions. Among comparable three piece hardside sets, the Merax three piece ABS set, the Coolife three piece set, the UKEIN three piece spinner set and the Coolife YD13 set cover the same ground, and the LONG VACATION six piece set goes further.

Who should buy it and who should not
Buy it if you want three matching nesting cases with reinforced handle mounts, TPU wheels and a recognized lock, and a very large body of buyer feedback reassures you. Do not buy it if you need the 20 inch case measured before you commit, since no dimensions for it are published; if you fly carriers that enforce 62 linear inches, because the one published figure exceeds it; or if you want a named manufacturer and a warranty to fall back on, since neither is recorded.
