So the potential buyer needs to be aware of prior use.
We have no idea know why this business went defunct -- we acquired this domain via auction -- or why the owner didn't sell his business (with the matching domain name and trademarks). Instead, the owner allowed the domain to go into the expiration/auction cycle (2015) and the three trademarks to expire in 2010, 2012, and 2014).
Perhaps physical assets were sold and the business renamed; this is something a potential buyer might check out.
Please consult with a trademark attorney or expert for how this domain may be used in commerce and whether or not Cookie Bloomers could be re-trademarked by a new owner.
Rather than trying to explain what Cookie Bloomers were and could be again, just take a gander at Google Images.
This aged domain has been continuously registered since 1995, having retained its original 1995 registration date/status through its expiration/auction cycle.
