Williams, from Houston, Texas, snagged the women's world record for the longest fingernails in 2017, when her fingernails were 18 feet, 10.9 inches .
But, before Williams got them cut over the weekend, she broke her previous record, with her nails measuring a total of 24 feet, 0.7 inches , according to Guinness World Records .
The fingernails on Williams' right hand measured 338.5 cm long, while the fingernails on her left hand measured 395.05 cm long, according to a press release provided to Fox News.
The nails will be put on display at Ripley's Believe It or Not! Museum in Orlando, Florida, according to a press release provided to Fox News. The display is set to debut on Friday.
They were measured one last time before they were cut off - 733.55 cm .
She had to rest them on cushions when asleep to ensure they didn't snap off.
It's gonna be awesome," Williams told GWR. "It's going to be like a wax of myself even though it's just my nails. I can't wait to see that, for real. I'm going to be grinning from ear to ear. Just really think about it, it's amazing."
In a statement in the press release, Williams added: "It's history for my kids and my grandkids. It's very exciting."
According to GWR, Williams hadn't cut her nails for 28 years, since the early 1990s. Before she got them cut, she had to be very careful with certain tasks and was unable to do others, like washing dishes or putting sheets on the bed.
With my movements I have to be very, very careful," Williams told GWR ahead of her nail cutting. "So usually in my mind I'm already preparing for the next step that I have to do to make sure that I don't hurt myself with my nails - or break them. I'm excited about cutting my nails because I'm looking forward to new beginnings."
Painting her nails was also a huge task before she got them cut. According to GWR, it took several days and three to four bottles of nail polish. In 2017, when she was first named the woman with the longest fingernails, it took two bottles of nail polish and 20 hours.
MAN HAS LONGEST FINGERNAILS IN THE ENTIRE WORLDShridhar Chillal is an Indian man from the city of Pune, who held the world record for the longest fingernails ever reached on a single hand, with a combined length of 1000.6 centimeters . Chillal's longest single nail is his thumbnail, measuring 197.8 centimeters . He stopped cutting his nails in 1952.
Although proud of his record-breaking nails, Chillal has faced increasing difficulties due to the weight of his finger nails, including disfigurement of his fingers and loss of function in his left hand. He claims that nerve damage to his left arm from the nails' immense weight has also caused deafness in his left ear.
Chillal has appeared in films and television displaying his nails, such as Jackass 2.5.
India's Shridhar Chillal has made it to the Guinness Book of World records for the longest fingernails on one hand ever. Chillal, who has not cut his fingernails since 1952, said that he has paid a price for his terrifying talons. The combined length of his fingernails is 909.6cm and one of his thumbnails alone is two metres long, The Mirror reports.
The 78-year-old said that his nails were nothing but trouble in his younger years. He has also offered to dedicate his nails to a museum. Chillal's passion of growing his nails started when he was beaten up by a teacher in school for breaking one of his nails and was told that he would never understand the kind of care required not to break them.
Shridhar said that his family members opposed but he decided from that point on that he would never cut his nails again, adding that this was the biggest goal in his life.
On 11 July 2018, Chillal had his fingernails cut with a power tool at the Ripley's Believe It or Not! museum in New York City, where the nails will be put on display. A technician wearing protective gear cut the nails during a 'nail clipping ceremon'y.
