Alfa Romeo Valve Caps 'Marchio Monocromo'

Great look, gr8 little detail. Good quality. But poor design - they have aluminium thread. Had to change two valves because they just could not be unscrewed, not even with heavy-duty pliers and WD-40. Once the metals stick, you can only cut them from my experience. Maybe they work fine if you grease the threads. Still, they look great, a nice little touch, especially with nice rims.
