I'm a huge fan of this toggle, it's light but well made and makes for an interesting clasp that contributes to the overall aesthetic of the jewelry. After receiving this one, I went back and purchased these in other metals for use with other pieces.
The clasp is one sided, but the unfinished side is not particularly obvious in this design in my opinion.
This is a great clasp for use in a nature-inspired piece and/or one that calls for simplicity without being boring. I used it on an organic-oriented necklace of jade (color) and roundels in shades of carmel. The overall look feels "clean" and summery. I will definitely use it again.
