There are two routes to go here:

Science route: kidney stones are largely made of calcium, oxalate, urate, cystine, xanthine, and phosphate in our world. Presuming dragon physiology is roughly the same as our world, there’s nothing inherently special about these elements in game. Short of “reliquary” type of usages (think finger bone of a saint), there’s no reason to think it is special. Considering dragon scale is used in armor, I have to assume any less exciting dragon “parts” would pale in comparison. Might have value as a trade good or interesting conversation piece to the right collector.

Fun route: this chunk of phosphorus can be used 1d8 times in place of normal phosphorus from your material components pouch, upping the damage die of any [fire] spell cast using it.

If we’re adding somewhat related concepts OP might find interesting, I’ve always thought these were neat: grammatically correct sentences your brain doesn’t process the first time.

Clearly the solution is 3D print drawer slides and a little handle so they can effortlessly slide out of the cabinet. Maybe even a pivot so they can angle down and lock in place for easy perusal and selection.

Can you rotate them 90° and get a ton of functional space back in your cabinets? Seems like pretty inefficient use of space currently. Very tidy, regardless.

Also, have you used sheets? Hot shit compared to the fucking powerhouse that excel is.
