For my job at work I am required to use a china/grease pencil to do my job... this is so much better of a product than the ones you need to peel off, plus it comes with a pocket clip on each pencil.Just what I orderedI absolutely love these. You don’t have to worry about unraveling the paper off as you would with the older ones. I need them for my job so I’m able to screw it down, mark and write. It’s very easy to change out the lead. I would definitely buy more.Use this at work , almost every day. So much more convenient and durable than the paper & string China Marker. A bargain for the Price. Excellent product & made in America, what more could You ask for?I love these marking pencils and use them constantly. I first bought a box of the assorted colors a while ago to use directly on the side of my plastic garden nursery pots so I wouldn't have to constantly stop and make plant tags as I am repotting. I use the white or yellow tpencil here.Turns out with all the different colors I can also use the darker colors to mark things in the kitchen like for dating and identifying jars or containers of food. I use glass jars a lot in the refrigerator, freezer or the pantry and they will write on glass, rigid plastic tops or metal.The writing points on these are not sharp, in fact they are somewhat dull so the writing comes out somewhat thick and not super neat but it is legible and oh so convenient and inexpensive.So why use these instead of markers? Because you can easily rub it off with a cloth and then throw it in the dishwasher or handwash it and then reuse the item. No labels or tape to put on and then take off. The information will stay on there until you rub it off.I prefer these over standard grease pencils; they're a lot more convenient for my work! The color quality is a lot more visible, too, over the grease pencils I was using before.They are handy for highlighting great passages in my other books too. And, they don’t bleed through the paper.Bought these to label breast milk bottles for pumping, storing, and feeding. I am SO GLAD I did. These are really clean, easy to use, and way better than the paper wrapped grease pencils! I can jot down the time on the outside of a bottle if she didn't finish it too, so no more "I wonder how long this bottle has been sitting out." And I love that there is a little clip. I clip it onto the side of my Medela Advanced Pump in Style so that I can label each bottle with a quick date and time, and it doesn't get messy or all over the place. I decided to use white instead of black so that if it rubbed off on clothing or other surfaces, it would make less of a stain. These Listo pencils aren't super greasy though, and the writing stays put till I wipe it off with a dish sponge. Might have been the best baby parenting idea I've had yet!I was looking for the markers they use at my work as they are always losing them and running out, and these are the same brand.My only complaint would be they are a bit expensive.Works great for my purposes at work.
