It's a nice box but I actually liked the old version better that fit in a rack.

A long time ago I found some cheapo clear plastic storage boxes with removable dividers at ACE Hardware for $.99 each. I ditched the add-in dividers and use them for bulk thread and other spooled material storage. Each box will hold 30 spools like they were made for them. Unfortunately, I should have figured out that the $.99 price was due to discontinuation from both ACE and the manufacturer.

My "working" thread is kept loaded on the two zillion bobbins I have.
