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.
I love my Chibi needles and case. The case helps me keep from losing the needles. I also like to put a large safety pin or rather a safety pin made from a paperclip through the case lid and attach stitch markers to the lid to keep those handy, too. I asked for a second set for Christmas after misplacing the case and everything and then yesterday found it in a forgotten pocket in my knitting needle wrap.
I love the needle size to use for yarn and the bent tips and even the copper color. I only wish they were actually magnetic so they'd be easy to find if I drop them through my recliner. Lately I want everything magnetic for this reason! ;o)
