Yep, thanks. It's embarrassing to admit, but I didn't know the clasp could be opened by sliding that little latch. And now I do, the JB Is even better for it!
Question, can the end with the latch on it fit through the rectangular keeper at the end of the other bit?
No, it cannot slide through the rectangular keeper. For me, I think the JB is much more secure once it's slid over the hand and onto the wrist. I can unclip the fastener and let the bracelet slide down onto my hand and it will not slide off until I close my hand tight to slide it over.
