I’ve been using these pencils for at least 10 years. They last forever, but one broke, I lost one and was down to my last one. I tried in vain to find more, and did buy other types (only Pentel bc they’re the best), but none were comparable. In the middle of the night, I couldn’t sleep, I thought to check the Pentel site. Voila! You had them! I ordered 4 and erasers, they arrived quickly, and were carefully packaged. As a teacher when you find a great pencil you stick with it. Please keep making these pencils!
