This designey Enna oil cruet was designed by Martinelli Venezia, the design firm of architects Carolina Martinelli and Vittorio Venezia.
This objet d'esign is billed as being "easy to refill"...
...but I'd argue against that; because the object is opaque, how would you know when to stop refilling?
While I don't deny the object is attractive and stylish, if easy refilling was the priority, I think the lid ought be removable, so you can see inside the thing as you're refilling it. But I realize a removable lid would mean you can't have that elaborate handle. So I guess it's a matter of what trade-offs are acceptable to you.
