Single piece of leather. Includes one refillable/replaceable Purell 1oz hand sanitizer (seriously–just buy a big bottle, keep it under the sink, and refill this wee lad every now and then). Keep it close by and you won’t be (such a) dirty, dirty person. Unless that’s your thing, which is cool–you do you, but you can also be less germ-y.
Clip it on your keyring, lanyard, or bag. Because those silicone jelly things are just damnably hideous.
There are dozens of these types of products on Etsy. The FFF model looks nice of course. As to whether or not the cost is worth it is up to the individual.
I carry this with me everywhere. Having the clip is great because I can clip it to my work bag.
