Cardiff Blues have confirmed Wales international trio Bradley Davies, Leigh Halfpenny and Chris Czekaj have signed contract extentions.
The Blues had already secured flankers Sam Warburton and Martyn Williams and centre Jamie Roberts to new deals but have now tied down three more stars.
"I'm really pleased to have extended my stay," said Wales wing Halfpenny.
Dafydd Hewitt, Josh Navidi, Andries Pretorius and James Down have also signed Blues contract extensions.
Halfpenny, who made the first of his 50 Blues appearances, at Ulster in May 2008, has won 19 Wales caps since his international debut against world champions South Africa in November 2008.
The 22-year-old has scored 16 tries in his Blues career - including two touch downs in the Welsh region's EDF Energy Cup final win over Gloucester in 2009 and in their Amlin Challenge Cup final win over Toulon in 2010.
Halfpenny, who has scored seven Wales tries, was included in the British & Irish Lions squad for the tour to South Africa in May 2009 but had to return home from the Lions tour because of a recurrence of a thigh injury.
And now he has committed himself long-term to the Blues, saying: "It's a great club and I had no doubt that this is who I wanted to sign with and happy that we have come to an agreement.
"I've not been tempted to play anywhere else as it's a very ambitious club and the quality players we have here, with some good youngsters coming through, the future looks very bright.
"We are seeing the Welsh talent coming through and it's great that they have decided to stay with the region."
"We won two titles in the last two years but we still have ambitions of winning more in the future which is why most of the players have extended their contracts."
Second-rower Davies, meanwhile, is now a senior member of the Blues and Wales pack since captaining the Wales Under-19 team to the Grand Slam in 2005.
The 24-year-old 6ft 6ins powerhouse has made 79 Blues appearances and won 22 Wales caps since his international bow in the 2009 Six Nations game with Scotland.
"It's great news to have signed, not only for me personally, but for the rest of the boys who have signed also," said Davies.
"It's nice that we have got a core of young players who have extended their contracts and can drive the region forward.
"I think our academy system is showing its worth now, a lot of the boys have stepped up and played at a high level, either Heineken Cup, regional rugby or international level."
Wing Czekaj, who is set to make his 100th Blues appearance against the Ospreys on Saturday, has won nine Wales caps since his try-scoring international debut against Canada in June 2005.
The 25-year-old, who has scored 22 tries in his Blues career, said: "I've been six seasons with the Blues now and I'd be stupid to want to move with the progress that the team has made over the last few years.
"I've really enjoyed the move from wing to full-back this season and I prefer playing full back now to be honest, so that's where I see myself from now on."
