Meetory 4 Pack Translucent Pen Cases,2 Styles Eraser & Pen Sharpener Plastic Storage Holder Box for Kids Students School Office Supplies, Candy Colour 2 Sizes

Great for sorting out pencils and pens

We use for school as needed to have clear pencil cases Worth noting that two are longer than others and can be tricky for kids to open at first

It's a box

I purchased these to organize my crochet hooks but they work for other items too. 2 of them have a small compartment that allows you to keep yarn markers or any other small item. And they close tightly.

Great little boxes. I use them for drill bits color-coded by type.
