These are awesome! I had a cheap plastic darning needle before and have just left ends in tucked away, of course since I hated working with it so much. I caved and got these and they are so easy to work with and it's impossible for me to lose them something I'm very good at with the screw top case! Love how they come in three sizes for whatever weight I'm using.
I haven't used a bent tip needle before and I'm finding it very handy. But, the really great thing about this product is the case. I've tried to keep my needles in one place, but I've had a hard time. The screw-on cover and easy to find case makes it possible to keep my needles in my little knitting ditty bag while still being able to find them and not having them poke through the bag.
