From the manufacturers website:

"Introducing new SuperDuPer DP Tubes™

We had some customers request that we make a larger DP tube to hold these larger size needles, so we did! Now knitters who use #10.5 thru #13 DP's can organize and protect their larger needles.

Our new DP Tubes will hold complete 5 needle sets of the following US sizes:

10.5 (and smaller sizes)
10.75
11
13
15 (4 needles)

Specs

SuperDuPer DP Tubes have a 1.0" inside diameter which is enough space to hold up to 5 #13 needles.
Our original DP Tubes have a 5/8" inside diameter and they can hold up to 5 #10 needles.
SuperDupers are based on a telescoping paper tube design just like our other tubes.
They will hold up to 10" long needles. Paper color is purple and yellow and is glossy.
