Use Distribute
A = Range[5]; B = Range[5] + 10;
Distribute[{A, B}, List, List]
gives
{{1, 11}, {1, 12}, {1, 13}, {1, 14}, {1, 15}, {2, 11}, {2, 12}, {2,
13}, {
2, 14}, {2, 15}, {3, 11}, {3, 12}, {3, 13}, {3, 14}, {3, 15}, {4,
11}, {
4, 12}, {4, 13}, {4, 14}, {4, 15}, {5, 11}, {5, 12}, {5, 13}, {5,
14}, {
5, 15}}
