These are individual, single, solid core potion bottle dice, not a set of dice. There is a separate listing for liquid core ones. 

Choose the piece you want from the drop down menu. If there are any problems or balance issues it will be marked (discounted) and there will be a description below.

You can request to have the numbers painted gold or white as well as have the cork painted at no charge by leaving a note. 

Green d4 has a cat hair in it! Balance is not effected. 
Sepia d4 has a small drop of resin that fell on one side after casting. Balance may or may not be effected.
Sepia d20 has a casting error that deformed the cork slightly that may cause balance issues.
