What's the difference between a cheap suitcase and a long-lasting one? 5 points to distinguish a suitcase that will last a long time

Title

If you open an online shop, you'll see rows of identical-looking suitcases, ranging in price from a few thousand yen to tens of thousands of yen. You might be tempted to choose one thinking, "They all look the same, and they're cheap, so I'll just go with it," but in fact, the price difference hides crucial differences that will affect the comfort of your trip.

Even if you manage to buy it cheaply, if the wheels break during one trip or the body cracks at the airport, you'll end up paying a lot in repairs or replacing it.

This time, we will explain the difference between "cheap" and "good" using five checkpoints so that you can find a suitcase that you will still be glad you chose 10 years from now.

一、チェック1：素材の「質」が違う

The material of the body has the biggest influence on the price of a suitcase.

Even though they may look like the same plastic at first glance, the contents are completely different.

█ 割れやすいプラスチックか、しなやかな「ポリカーボネート」か

Many budget models use a hard plastic called "ABS resin."

It is easy to process and inexpensive, but has a tendency to break easily when subjected to strong impact.

On the other hand, a common material used in good suitcases is polycarbonate (PC) .

It is so impact-resistant that it is even used in bulletproof shields, and it is flexible enough to return to its original shape even when pushed hard, so it can withstand the rough handling of luggage at airports.

█ 軽さと強さを両立する「ハイブリッド素材」のメリット

The hybrid material "PC+ABS resin," which combines the "hardness" of ABS with the "strength" of polycarbonate, is also very popular.

New Trip suitcases are also made from this material, making them light enough to be carried with one finger, yet sturdy enough that an adult can ride in them without breaking them.

Another important point for keeping the product looking nice and clean for a long time is whether the surface has been embossed to make scratches less noticeable.

二、チェック2：ファスナーの「スムーズさ」が違う

One thing that is often overlooked is the quality of the zipper.

If the zipper gets stuck when you're packed to the brim or in a hurry, or if it suddenly opens and breaks while you're out and about, it can ruin the rest of your trip.

█ 旅先での「困った」を防ぐ、世界シェアNo.1の安心感

Many "good suitcases" use the globally trusted "YKK zipper." Compared to cheap, no-name brands, the smoothness of opening and closing is completely different.

New Trip also uses YKK products as standard, and the stress-free movement with light force is an important point that makes you think, "I'll use this again next time" after using it once.

█ 壊れにくさは「見えない部分」に宿る

A good zipper has a durable fabric portion (tape) that is designed to resist rippling and tearing even after repeated opening and closing. To avoid the disappointment of having to wrap your bag with duct tape after a trip because it's "cheap," the "smoothness" of a zipper is something you should always check.

三、チェック3：キャスターの「ブランド」が違う

Of all the parts of a suitcase, the ones that break down the most and make the biggest difference are actually the casters (wheels).

You might think, "They're all the same wheels, aren't they?", but if you skimp on this, it could lead to tragedy during your trip.

█ 安いものはすぐ摩耗する？「HINOMOTO」や「SJ.TOBOL」が選ばれる理由

Cheap suitcases often use casters from unknown manufacturers, and after a few trips the rubber can wear off or the axles can seize and stop the suitcase from moving.

On the other hand, high-quality models use casters from well-known manufacturers such as the Japanese brand HINOMOTO and the globally trusted SJ.TOBOL.

These require an incredible amount of precision to keep rotating smoothly.

█ 走行テストの回数が「長く使えるかどうか」を決める

Casters from reliable manufacturers are repeatedly tested over an incredible number of distances before shipping to ensure they will not break even when driven many kilometers over bumpy roads and hot asphalt with a heavy load.

It is these "named casters" that have passed these rigorous tests that will help you avoid unexpected trouble while traveling.

█ 移動の「疲れにくさ」に直結する

The smooth casters have no unnecessary friction, so even heavy loads can be moved smoothly with little effort. This minimizes the strain on your arms and shoulders, making a huge difference in how tired you feel after a day of moving around.

For a long and comfortable journey, the quality of the casters is an essential point.

四、チェック4：ハンドルの「ガタつき」が違う

One thing that is surprisingly overlooked is the construction of the handle (carry handle).

In fact, here too lies a hidden hint as to whether you will be able to use it comfortably for a long time.

█ 自分の身長にぴったり合う「段階調節」の精度

A good suitcase will have handles that can be precisely adjusted to any height.

If this is a cheap product, it may only have two levels of adjustment, or it may shake violently even when it is supposed to be fixed.

The handle stops exactly at the perfect height for your height, eliminating unnecessary force while moving, making it surprisingly fatigue-free.

█ 握り心地の良さが、移動の疲れを左右する

When traveling long distances, you will be holding on to the handlebars the whole time.

A sturdy model is designed to fit comfortably in the palm of your hand and is made of a material that is just the right thickness.

It may seem like a small difference, but at the end of your trip, the difference in "ease of grip" will make a difference in how tired you feel.

Title

五、チェック5：アフターサポートの「有無」が違う

The last thing you shouldn't overlook is what happens after you buy it.

█ 売りっぱなしの格搬品 vs 1年保証が付く安心感

Many cheap products are simply sold and then forgotten, and if there is a problem when you receive the product, they may not be able to help you.

On the other hand, manufacturers who are confident in their quality offer solid support such as a one-year warranty.

Knowing that there is a place you can go to for advice if something happens is a great source of comfort.

█ パーツ交換や修理ができるかどうか

When you say "Only one caster is broken"

If it's a reputable manufacturer, they will often be able to help you with part replacement or repairs.

Instead of being disposable, you can repair them and use them carefully.

These are the conditions for a truly cost-effective suitcase.

六、New Tripが「手頃なのに高品質」を実現できる理由

After reading this far, you may be thinking, "After all, high-quality products are expensive, aren't they?"

There's a reason why New Trip is able to offer affordable prices while using the polycarbonate, YKK zippers, and famous brand casters we introduced here.

This is because they are committed to "bulk production in their own factory" and "direct online sales."

By cutting unnecessary intermediate costs, we can keep prices down without compromising the quality of the contents.

New Trip is proud of this "golden balance between price and quality."

まとめ：安さだけで選ばない。5年後、10年後も一緒に旅ができる相棒を

Once you buy a suitcase, it becomes an important companion that will accompany you on your travels for several years, or even for more than 10 years.

It would be a shame to choose a car just because it's cheap and then run into trouble while traveling.

Check out the five points we've introduced here and choose the one that best suits you.

May your next trip be more comfortable and free with your trusty suitcase!
