"If the item is used and has a flaw, once you select "Used" from the drop-down list, you should then be able to type in the blank field whatever you need to regarding the condition. (image attached). "

You have understood exactly what I meant - thank you!!  

After I select "Used" a field opens which says "Used: An item that has been previously used etc"  and it is here that I want to insert the statement, but no blank field opens up and I cannot work out how to get the field blank!!  I have tried deleting the text that is there which does not work but I cannot find a blank field as pictured in your image.

Bella - as the link shows - it is two separate fields.

Select - Used.

Then the box below to describe.

You can't get rid of their description - ie an item Bla Bla.

Otherwise select - New - but make sure in your description you describe acurately.

I know they're two separate fields - I just can't find this mystery "blank field".

No blank field opens below "Used" or "New" or any of the other descriptors.

I also can't find any create your own field in Item Specifics!!

Maybe it's an option for high volume sellers!!

Here is what my screenshot looks like on starting a new sell.  

Condition

Used

Used: An item that has been used previously. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. This item may be a floor model or store return that has been used. See the seller’s listing for full details and description of any imperfections.

[No blank field]

I'm a bit further down the road with this because when you change the category of a product you get a different screen. 

So, what category were you in when you did the image of Condition - Condition Description?

I only use Chrome and only do ebay business on my laptop.

I don't know what the problem is, but I'll keep working on it.

Thanks for your help!
