Here is a picture of mine filled with supplies:

Z4131 Exclusive Inks Organizer $69.95
Z4135 Re-inker Tray sold separately $8.95

As you can see I used labels on the side of the organizer so I would know where each ink color belongs.  My kids will use them and not put them back in the right spot or I will take out a bunch and can’t remember where they go.  I have mine sorted by the CTMH color families with the Neutral colors on the bottom.  The best deal is to purchase the entire organizer (or earn it as a 1/2 price item with a qualifying gathering) but you can also purchase it in pieces as you need them.

Z4132 Stamp Pad Tower $11.95
Z4133 Marker Tower $14.95
Z4134 Handle and Swivel Base $15.95

I purchased the Re-inker Tray way before I bought any re-inkers.  This tray can be used for anything!  Throughout the years I have used mine for a variety of things including embossing powders, other ink pads, sponges/daubers, and glitters.

Another item that goes along with this that I like is the Z4136 Organizer Carrying Case $34.95.  If you travel and take your supplies with you it is a worthy investment.
