You can use these jars for SO many different things. I am a hairstylist, and I don’t want my barbicide to be out on my counter where you can see it so I actually clean my combs and my shears in this jar.. it’s so black and made so well and so sturdy. It is isn’t the most seamless way to do this ..I am dipping the combs or my clips and my guards in there by hand and kind of rinsing them and taking them out all by hand. However it’s so worth all the trouble because it is so visually pleasing, and the quality is unreal. It’s mars black and so visually beautiful in my salon I’m obsessed get them. I’m going to order more to store coffee beans in!!! Shipping came so fast don’t hesitate to buy them!
