Scarlets have agreed new contract terms with front-row trio Peter Edwards, Wyn Jones and Dylan Evans, the region confirmed on Tuesday.
Tighthead prop Edwards, 35, will mark the beginning of his sixth season with the team going into 2016/17, having made his debut in 2010.
Despite suffering an elbow injury in the Champions Cup clash against Racing 92 in November last year Edwards has proved to be an important part of the region's front-row, making 17 appearances thus far this season.
One of Scarlets' homegrown talents, Jones, 24, has made 88 appearances for his home club Llandovery, scoring nine tries over six professional seasons with the Principality Premiership side.
Jones' first regional appearance came off the bench against Gloucester in a 13-7 victory in 2013/14. He went on to make 13 appearances for the Scarlets in 2014/15 including in Champions Cup clashes against Leicester Tigers and champions Toulon and will look to kick on in the Scarlets jersey with a new two-year deal.
Australian born Evans, 27, joined the Scarlets ahead of 2015/16 season and has signed a new deal that will keep him at the region until at least June 2018.
Scarlets General Manager of Rugby, Jon Daniels, said; "We are delighted to be in a position to confirm that Peter, Wyn and Dylan have all extended their contracts and will remain with us here at Parc y Scarlets.
"Pete has been a stalwart in the last few seasons offering much needed experience and support to the emerging international talents of Samson and the likes. Retaining players of Pete's experience is important as we look to continue the development of young props at the region. Both Wyn and Dylan have worked exceptionally hard and are looking to challenge for regular game time in the regional shirt."
