This case holds 7" and 8" dpns (as opposed to the 6" sock dpns). There are a couple of gaps in the sequence (no 7" -3.0mm needles, for instance), and some odd duplications (I hardly ever use Size 4 needles, and yet I have about 5 sets of dpns in that size). I remembered to make the right-hand side pockets wider for the size 9-13 needles this time.
Between these four roll-up cases, and the three notebook binders, I should be able to lay my hands on whatever size needles I need, whenever I need them.
That is, of course, if I don't forget where I put them away.
