North Korea's latest missile test may have put most of the world on edge - but South Koreans are now being offered peace of mind with these fallout shelters.

Firm Chumdan Bunker System has just opened a showroom in Seoul in order to sell the £20,000 containers which promise to keep people safe if a nuke falls.

Each bunker comes equipped with four beds - though can be modified up to eight - its own air filtration system and solar panels for power.

Go Wan Hyeok has created what he claims is South Korea's first fully-nuclear proof bunker to provide safety in case Kim Jong-un launches an atomic warhead

The bunker, which costs around £20,000, is equipped with enough space for four people - though can be modified to take up to eight

It comes equipped with space for a computer and TV, along with solar panels and self-winding generators in order to power it (left). Bathroom facilities are basic but include a chemical toilet, shower, and basin (right)

Dehydrated ration packs initially designed for NASA astronauts are included in the package along with a full medical pack and safety gear for navigating the post-apocalypse world

Also included are basic survival tools and some more specialist gear such as gas masks and hoods to protect against acid rain

Owner Go Wan Hyeok said that since the latest test, which happened early on Wednesday, his sales team have been struggling to keep up with demand.

The bunkers also have self-winding generators to provide electricity for up to a month, a fridge, computer and periscope to check when it's safe to come out.

Dehydrated ration packs developed for NASA astronauts are also supplied, along with gas masks for the family and suits to protect against acid rain.

There is also a chemical toilet, shower bag, and sink allowing waste to be drained outside without the occupants being expose.

Mr Go said: 'I started the company in September, but I’ve been researching this for a long time and travelled all round the world.

In the case of a nuclear war the bunker has enough electricity to last for a month, after which the occupants will be forced to venture above ground

The bunkers are designed to be buried underground, and have to be transported to the new owner's property by a crane

Excavators will be brought to any buyer's house in order to dig a hole large enough for the capsule to fit inside

Once submerged the pod can be accessed through a hatch in the top, keeping them isolated from the outside world

'Before, they were not radioactive-proof in Korea, and very expensive, then after spending time in Switzerland, the US, Australia and the UK, I came up with the most perfect bunker.

'I did everything to build this. I researched all the products and it's completely unique. This showroom is for people passing by who want to buy one.

'These bunkers are everything-proof. Outside the military, this is the first bunker like this available for civilian use.'

Mr Go added that he now has plans to expand into Europe and the UK market, as Kim's new Hwasong-15 missile puts Europe within range for the first time.

The estimated maximum range of the ICBM, which is the most powerful North Korea has ever tested, in 8,000 miles.
