If you're looking at the ink pads like this, then you won't have a problem. But if they're stored in a whirly-gig thingy then you can't actually tell what's what without removing them from the shelf.
So Stampin' Up! has attached sticky labels to the bottom of the casing.
Simply remove the label and you can choose the appropriate one - or the one you like the sound of ;) -
then adhere it to the end of the case.
Once the ink pad is open, it can be difficult to tell which colour is which, so this little tip came from Convention; cut the ends off one of the other labels and affix it inside the casing.
That way, if you're using more than one colour at a time (mostly, I know!), you'll not mix up your colours.
Voila! Enjoy using your labelled ink pads.
