Conor Ahern, Eric Donovan and Roy Sheehan have been selected to represent Ireland at the multi-nations event in Finland this week.
All three are hopeful of medals which would also secure their places on the team for the World Championships which begin in Beijing on November 11.
Kenneth Egan and Darren Sutherland have already been selected for the Championships.
Ahern (51Kg), Donovan (57Kg), Sutherland (75Kg) and Egan (81Kg) all landed gold medals earlier this month at the multi-nations in Albania, when they went all the way on an incredible night for Irish amateur boxing.
