Two brothers in Exeter, southwest England, have been gifting each other birthday presents which are incredibly hard to open as part of an ongoing prank.

This year saw Jordan give his brother Kieran a T-shirt encased in a layer of concrete. Kieran was forced to use a hammer and chisel to slowly pick away at the 12 kilograms of concrete to get his hands on his gift.

Jordan told Newsflare about the prank which has been happening for at least five years: "It started with just extra sellotape and then Russian egg style boxes. Last year we started using cable ties. This year was the first concrete gift."

"As it stands I’m looking to do so some welding for Christmas," he added in another post.

Jordan's posts on Reddit have received over 100,000 upvotes between them.

This footage was filmed on October 26.

Every year my brother and I compete to gift a present that’s hard to unwrap. This year I wrapped his gift in concrete

I’d say about 5 or 6 years. It started with just extra sellotape and then Russian egg style boxes. Last year we started using cable ties. This year was the first concrete gift
