I am a bridal hairstylist and I have been searching for the perfect container to hold my Bobby pins for 10 years and nothing has ever been quite right until this! It is the perfect size for travel and holds all of the pins I need for an event.This help me organize all of my small trinkets in my home office so this was greatThe plastic is not terribly thick but it gets the job doneThis is great for any hobby or project with small parts. I use mine for storing and organizing small parts for beer brewing, but I'm sure it would work well for many other applications.Vertical dividers can be removed to fit longer or bigger items. It closes securely and allows to see items inside. This is very handy to have.I got this for some a huge embroidery floss package I had coming, mainly because the other three that I have are completely full and it was desperately needed.The title of the item specifically states 'with Adjustable Dividers', which is what drew me to this organizer, I don't organize my floss by number, I do it by color. There are no adjustable dividers, there's not even any notches for dividers, there's just eighteen large squares and that's it. I might have been able to forgive it if it weren't for the fact that this organizer wasn't even designed for additional dividers because of the lack of notches to hold the dividers in place. Extremely disappointed.Excellent price and perfect size.
