This seemed perfect to keep attached to my interchangeable needle case. I was disappointed to discover that the size of at least one of the holes is inaccurate. When I measured several loose needles so I could replace them in the case, all eight passed cleanly through the size five hole. When I re-measured using both a Susan Bates and a Knit-Picks sizers, they revealed that I correctly had two sets of size five and two size six. Except as a zipper pull, the Debra's Garden sizer is of no value if I can't trust the measurements.
This is just what I needed. I have needles from misc. manufacturers and unlike the Addi circular needles or some straight needle companies - they aren't marked for size. I know there are needle gauges that are less expensive and plastic and they work but this is functional, sturdy metal and it really looks so pretty! It's also a nice compact size so you don't have a utility looking rectangular plastic thing lying about. I like that you can use it as a pendant - it almost looks like a pretty slice of a seashell shape. The numbers aren't just printed on - they're engraved so they won't wear off. This was very well thought out to give knitters a quality made tool that is also very good looking.
