This competition has now closed. Congratulations to the UK-based winners, who are Peter Chicken from Hull, Sarah Griff from Bristol, Amanda McCormack from Devon, Kat Comer from Wirral and Michael O'Sullivan from London.
With entries limited to our UK-based readers, five winners will receive a 35-litre suitcase each. The brand will choose either a navy or black case for the winner.
Measuring 54 by 37 by 23.5 centimetres, the suitcase weighs 3.5 kilograms and has a capacity of up to 35 litres. The two exterior zips can be clipped into a TSA-approved luggage padlock found on the side of the suitcase.
Inside, a flat, mesh-covered zip compartment covers one side of the case, with an elastic compression-strap securing the contents on the other.
Lifting the adjustable handle to the preferred height reveals an in-built stopper, which can be pressed to lock the wheels into brake when needed. The case's wheels have also been developed to roll quietly.
As with all Muji products, according to the brand, the Muji to Go collection's practicality and quality mean its products can be used over and over again with ease.
"The Muji to Go range is designed to take the hassle out of 'getting there' and comes in enough varieties to tailor to the individual needs of your trip," explained the brand.
Muji identifies three main stages within any trip: preparing, travelling and arriving. Each of its travel products are designed to help ease each part of the journey.
Customers can prepare by filling their Hard Case Trolleys with gusset cases, travel-sized toiletries and refillable bottles from the collection to efficiently pack the essentials for their stay.
Other products, including a micro-bead neck cushion, slippers and eye masks are also offered for comfortable travels.
Muji has also designed for arrivals, when travellers often undergo a "ritual of settling in before setting off".
Compact electric toothbrushes, portable hair dryers and toiletry cases are available to bring a sense of home whilst being away.
Items are designed to be lightweight, ensuring travellers can pack various items into their luggage without exceeding weight limits.
MUJI was founded in Japan in 1980 as an antithesis to the habits of consumer society at that time. MUJI envisions user-friendly products that bring out the beauty in modest simplicity.

Five UK-based winners will receive a 35-litre Hard Case Trolley in navy or black, at the brand's discretion.
Competition closes 1 January 2020. Five winners will be selected at random and notified by email, and his or her names will be published at the top of this page. Entrants must be from the UK only.
