I like these holders because you can knit on to them and knit off, if you are so inclined. The best feature, however, is that you can remove stitches from either side without a problem. They have also held together very well, even with a tug here and there from my little ones.
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.
