Although the jumbo eye pencils come in beautiful colours, they crease like crazy within a few hours of application, I've tried everything, from setting it with a powder to using a base, I have not tried my concealer as a base for it yet, so when I try that I'll get back to you. However for now this is a no go in terms of a cream eyeshadow, however as a highlight on the browbone or innercorner these work fantastically.
In the end it all depends on how you want to use it.
