The colorful crochet hooks came by mail and are cleaned up in a transparent case. Needle size 2.5 and 3.0 have the endurance test behind them, in cooperation with a Strickliesel) Test has been successful, because despite effort (sometimes) to lift the loop over the hook, the needle is not bent. What now does not necessarily mean that it would not go - bending) The hook engages well without interlock. Am satisfied and happy :)
