Visibility is a design choice: hidden-loop bails are engineered to disappear behind the pendant, while architectural bails are meant to be seen and read as part of the front-facing composition.
Made With Purpose
The tube bail developed as an alternative to the loop bail by redirecting the chain's path from vertical loop to horizontal passage through a cylinder. The weight distribution is across the full tube width rather than at a single point. The result has a different profile at the connection point and a different hang angle for the pendant than a loop bail.
Built For Ease
Independence matters. The lobster clasp's compact design and lever mechanism make it one of the more practical closures for self-fastening. The person you're giving it to should find it manageable to put it on without help.
