I’ve become quite dropsy and clumsy with Vestibular disorder; amazon.com to the rescue!
There are mini pool noodle type grips for things like perfume rollerballs and smaller sizes. called “Vive Foam Tubing”.
Notice that the sizes for “Belle” and “Sí” parfum aren’t standard.
Not a problem: just cut the length you need, gently put into the “noodle” and label with a black Sharpie.
Great for extra glass protection while traveling too.
