Luggage set by Delsey in blue color. They are made of polypropylene, a durable plastic polymer, known for its high impact resistance. These suitcases, if dropped or bumped during travel, are less likely to be damaged or crack. Additionally, they are waterproof, so even if it rains, your luggage will remain dry. They feature a lightweight design (lighter than ABS) and facilitate the transport of more items without worrying about weight limits. They are a suitable choice for those who travel frequently or travel with many or sensitive items.
