My daughters Cassandra strap came loose. We screwed it back in with some “”Locktite” which is made for glasses screws. No problem since then. These small screws sometimes do this. It is so easy to strip them when tightening.Hey, has anyone had a problem with the screws coming out on their penelope messenger? Was getting off a taxi today when my strap detached, and the screw fell off. Fortunately, I was able to pick it up but when i checked the other strap, the pin/screw was halfway out. I jammed them back in but am wondering when it’ll happen again. Have emailed Marco but wanted to check with the other Penny owners if this has happened before?
