Plastic Notion Case by Nancys Knit Knacks "Perfect Notion Case" in Blue
From the manufacturers website: "The Perfect Notion Case for knitters. Sturdy case with 6 compartments with see-thru lids."
These are truly the perfect notion case. Their compartments keep everything separated, no more tangled stitch markers, no more losing your darning needle. There are three colors available: purple, green, and blue.
This case opens from the bottom, then each compartment can be open or locked independently.
