In the rarefied world of high-end bong makers, Roor glass water pipes have long been smoked to impress. The status symbols are so sought after that some models command prices of $1,000. There’s even a diamond-studded, gold-gilded Roor that goes for nearly $4,000.

Both marijuana and the tools used to smoke it remain illegal under federal law, but that hasn’t stopped Roor and its American licensee from using the federal courts to protect the brand and its sales.
