Coming in at a diminutive 3.5 x 1.5 inches, the plastic carrying case fits all three items neatly and securely. No rooting around the bottom of a giant purse looking for that nail clipper you knew you threw in there at some point -- not any more. The small case is easy to find and even easier slip into an already crowded day bag. Or, keep it in a gym bag or in the desk at work. I'm sure you can think of a dozen places where this little guy would be useful to have around.
Although there are similar manicure kits available at drugstores, this one is priced a bit higher for good reason. All of the instruments are high-quality Tweezerman products, known for their durability and precision. And, indeed, the cuticle trimmer is sharp and exacting for snipping off those pesky hangnails before they cause major damage. One downside is that having this kit around makes it tempting to start to nip away at more of the cuticle than is helpful. So a certain amount of restraint is needed with the mini mani kit! Another nice feature is, with the exception of the file handle, the products are metal and can easily be sterilized in the oven or boiling water.
I would say that, in order of frequency, I use the file > under-nail cleaner > pushy > trimmer. This seems effective to keep my tips snag-free and on the way to a full recovery. Incidentally, nail rehab is going well and I'm encouraged that in another week or so I will be able to do a nail of the week (NOTW) without shame.
