You never actually own a Jonny Concrete door stop, you merely look after it for the next generation. They aren’t just a device for holding doors open, they're an heirloom that transfers values across generations.

They are also heavy and should not be used in place of a buoyancy aid, dropped on feet or thrown at windows or people.

'Its better to have owned a Jonny Concrete doorstop and had it stolen than to have never owned one at all.' Alfred Lord Tennyson's brother by another mother

If you follow our stories on Instagram (@jonnyconcreteuk) you may be lucky enough to find one of the square doorstops we leave around London for people to find. These are completely free for you to keep, no strings attached.

For those of you who can't be arthed to go looking or if you need a fine lump of contrete urgently you can buy our round doorstops for £45 each which includes delivery to UK addresses.

This is amazing value at under 0.0013p per day based on a 100+ year life expectancy.

For the sake of clarity, as King Alfred famously said 'THOU MAYEST NOTTEST PURCHASE THE SQUARE DOORSTOPS', you have to find these. You can only buy the round doorstops.

We can also personalise our round doorstops as gifts for birthdays, weddings, house warmings, funerals and other celebrations. This can make for a very original concrete doorstop present and will make the gifter the favourite child, relative, friend or guest. It can also make gifting a lump of old concrete a much more thoughtful and sensitive thing to do than might normally be the case.

Finally, because our doorstops are a highly collectable investment that will only go up in value (much like a crypto, but with upward only wild price swings) we date them so you can show yours was bought before your friend's.
