Wales have named 10 uncapped players in their 36-strong squad for the 2018 Women's Six Nations.
Ospreys trio Natalia John, Amy Thomas and Cara Hope, plus Scarlets' Beth Lewis and Cardiff Blues' Awen Prysor are named among the forwards.
Scarlets contribute three to the backs in Jade Knight, Angharad De Smet and Lisa Neumann, with Cardiff Blues' Hannah Bluck and Osprey Alecs Donovan.
"There's a fresh feel to the squad," head coach Rowland Phillips said.
"They've brought a real hunger and energy to training, which is infectious."
Wales have a warm-up friendly against Ireland on Sunday, 21 January in Ystrad Mynach (13:00 GMT) and begin the Six Nations at home to Scotland in Colwyn Bay on Friday, 9 February (18:00).
Phillips will have a depleted squad for that fixture, as seven players will be on sevens duty in Brisbane as they prepare for the Commonwealth Games in April.
So Wales have also named a development team of six players who will train with the senior squad throughout the tournament.
Phillips added: "Their presence will reinforce the squad. Even though they may not quite be ready for Six Nations rugby, they are players who we feel will benefit from working alongside the squad as part of their development."
