First, let's take a look at how the PP004 series can meet various needs through size design. This series of products includes 20-inch, 24-inch and 28-inch specifications, which are suitable for carry-on boarding, medium-range travel and long-distance travel respectively. Each size has been precisely calculated to ensure that it meets airline regulations and can accommodate enough items. Therefore, no matter how the length of your trip changes, there is always one for you.

Next, we will delve into why PP has become the star material in the field of modern luggage manufacturing. PP (polypropylene) is a high-strength plastic with the advantages of light weight and strong impact resistance. The application of this material makes the PP004 series trolley case easier to handle than the traditional hard case, and at the same time can resist damage caused by external collision. In addition, its waterproof performance also makes the contents of the box more safe and reliable.

Safety is essential for a good suitcase. The PP004 series is equipped with a customs-resistant lock system. This innovative design combines the international standard TSA password lock function with a special encryption mechanism to protect users' privacy even during cross-border customs clearance. More importantly, users can achieve double security by simply setting custom combination codes.

In addition to the above highlights, the PP004 series also achieves the perfect balance of "lightweight" and "durable. This is due to scientific and reasonable structural layout and technological innovation-the wheels are designed with silent universal bearings, which makes pushing and pulling smooth and effortless. The height of the handle can be adjusted to adapt to people of different heights. The internal stratification is clearly convenient for sorting clothes and other objects. All of these together constitute the core competitiveness of this cost-effective product.

In order to allow every user to take full advantage of the storage capacity provided by the PP004 series, here are a few tips for efficient packaging:

-Place heavier items close to the bottom position to lower the center of gravity.
-Use compression bags to reduce the space occupied by larger clothes.
-For wrinkle-prone clothing, you recommend fold it flat and put it into a special compartment to fix the shape.

Following the above recommendations will not only increase the usable area but also ensure a neat and orderly removal.
