I think gone are the days when everything inside a handbag should be in black. (Admittedly, I used to do that.) Something has to stand out, especially if they need to be ‘fished out’ every so often.
Some may find these key rings ‘bulky’ in the pocket. Not really, and I’m not saying that because I made them. For a tactile person, it’s reassuring to know that as long as I can feel the beads, the keys are safe along with them.
