China Glaze OMG: 15mL, comes in regular China Glaze bottles. The holoness shows up really well in the bottle, and any base coat for this polish will be fine. This polish is very hard to find, and the price range can be anywhere as $4 to $60.
Now, lets see what they look like!

(thumb Greta, index OMG)As you can see, China glaze is more subtle and soft as MUS is more radiant. They both have the same rainbow effect, just one is more softer than the other. I love both of these! I think Greta would be more of a regular nail use where as china glaze would look better as a stamping polish! what do you think?
