Edith Ritchie and Evelyn Middleton turned 102 on November 15, but they had to wait until this week for the real present.
Guinness World Records has named the centenarian sisters, who hail from Aberdeenshire, Scotland,the world's oldest twins.
“Edith and Evelyn are a remarkable pair," said Guinness World Records Editor-in-Chief Craig Glenday in a press release.
"When they were born, the likes of Mark Twain and Florence Nightingale were still alive, and we had yet to conquer the South Pole. They’re not just the oldest in the UK, they hold the world title. They’ve clearly benefitted from good genes, and a solid life-long friendship that only twins can truly understand.”
The sisters just edged out the previous record holders Ena Pugh and Lily Millward, who are still alive and kicking, just six weeks younger.
Although there are claims of 107-year-old twins living in the Ukraine, the Scottish sisters' claim remains the only record verified by Guinness officials, reported the Metro.co.uk.
The twins are not identical, but their mother always dressed them exactly the same, with bows in their matching long brown plaits, according to the Daily Mail.
After leaving school, the sisters worked on farms before leaving to start their own families.
Evelyn married William Middleton and had four children, 12 grandchildren, 26 great-grandchildren and three great-great grandchildren.

The sisters have remained close throughout their life and now live together at Bonnyton House, an assisted living facility in Ellon, Aberdeenshire, Scotland, and Edith credits their long life to three things: “Simple living, hard work and a good husband.”
