The ICE Canada Luggage Set is hard-backed and made from extra durable ABS (Acrylonitrile-Butadiene-Styrene is an opaque thermoplastic polymer material that is very strong and durable), and will ensure your belongings are safe and secure throughout your travels. All the suitcases are fully lined, so that your items have that extra bit of protection within the case. The built-in combination lock and padlock hole on luggage zips will also give you piece of mind that your goods are safe and secure at all times. Also has a mesh pocket so you can conceal even more items within the case. Boasting an extending telescopic handle and 4 wheels per suitcase, the Premium Luggage Set makes transport effortless. Should you prefer to carry your case, there are handles with ergonomic grips on the top and side of each case.
