Your Hulken can stay functional and in good shape for a long time. The best way to achieve that is to fold it whenever it is not in use. Your Hulken will naturally fold in one direction only. If folding to one side feels rigid, try folding to the other side. Folding your Hulken in any other way may damage it.

The current version of the Hulken rolls on 4 or 5 (depending on bag size) small yet powerful Stainless Steel wheels. It is true that bigger wheels give you the option to pull a bag up the stairs by yourself but we took a different approach with the Hulken design. We avoided big clunky wheels that are messy and tend to break easily so you will have the option to fold the bag completely flat for easy storage at home. In addition, we added 5 unbreakable handles (3 long ones plus 2 tight on the sides) to give more options for lifting when necessary.
Hulkens are made of polypropylene, polyethylene and 'memory fabric' which is a combination of several layers that keep the bag standing upright for simple and stress-free packing. The bottom board is extruded from recycled material. The swivel wheels are made of Stainless Steel. 
The recommended weight limit is 66 lb (30 kilos).
Hulken is built to last for a long time. Made of very strong industrial materials and Stainless Steel wheels, the bag can carry 66 lb (30 kilos) easily. Hulken was designed with rigorous industrial research and trials. Wear and tear may occur over time, especially if loading the Hulken frequently with heavy loads.
Hulken doesn't have a built-in cover (or zippers) but a specially designed Hulken cover can be purchased separately here.
Yes. However, Hulken is not waterproof, and is not meant to be filled with any kind of liquid.
Yes. The interior of the Hulken is non-toxic food grade under European Union standards.
You can wash your Hulken gently by hand, with warm water and a sponge. Do not put your Hulken in a washing machine.
Scrape off bits of debris and dirt with a butter knife or the tip of a screwdriver. A pair of tweezers can help you pull bits of hair and dirt from the caster's shaft. A bit of lubrication can help keep them rolling smooth. If the spray lubricant has a long small tube attached to the button spray, insert this tube closest to the metal shaft on which the wheel turns and spray a bit of lubricant there. Avoid spraying the face of the wheel that touches the floor, as doing so will spread lubricant onto your floor. Wipe excess lubricant with a clean lint-free cloth.
Wipe all surfaces, handles and wheels with a disinfecting wipe (such as Clorox) - this should not affect the bag's quality. Alternatively, the wheels can be sprayed with a disinfectant (such as Lysol).
Not at this time- we currently ship only in the US.
No. Hulken can't be used as a checked in luggage at the airport.
