Addi Rocket Squared Needle Gauge

Gauge to measure Addi Rocket Squared Needles.  Rocket Squared needles are, well, square, and you can't fit a square peg into a round hole!  So standard needle sizers don't work for Rocket Squared needles. Fortunately, there's a handy, custom-made too that works perfectly for Rocket Squared needles.  Keep it handy for your interchangeable set as well as all your fixed squared needles.  You'll thank me later!
