Luggage set by Playbags in blue color. They are made of ABS (Acrylonitrile-Butadiene-Styrene), a thermoplastic material that offers good impact and scratch resistance. These suitcases are slightly heavier compared to polypropylene suitcases. They are not recommended for frequent or long trips where increased durability and resistance are required, as ABS is a more rigid material and therefore more likely to crack or scratch over time, especially with frequent use.
