for the fun fact, the syringes in this look like antique syringes. they look similar to actual dental syringes which are also metallic, with the difference that dental syringes aren't graduated like the ones in the post, as this part is usually "hollow" instead and work with pre-filled cardridges, not by sucking in the liquid manually like other syringes.
Hum. What does the [OC] commentary tag actually mean in this context? I always thought it meant "original character" but that's obviously not the case here.
