<p>Personally, I like the Staples brand ones. They’re really cheap. The little clip things do fall off after a bit, but I don’t mind. If you don’t like that, then don’t listen to me. I just take the erasers out and use one piece of lead at a time (I carry a case of it in my pocket all the time for refilling emergencies). They last a while as long as you don’t lose them (like I do)(hence my username lol).</p>
