This is the third one I bought and added to my collection. By this time, I was already hooked on collecting. I searched eBay looking for similar black mechanical pencils. Then I remembered that in college in the Philippines there were 2 popular brands when it comes to drawing pencils: Staedtler and Rotring. Each was packaged in a college set with 3 Technical Pens, an eraser and ink. The Staedtler Micro pencil was easily recognizable with its blue color while the Rotring Tikky had the familiar brown color with the wave grip. I didn't like the wave grip on the Tikky since it felt like it would hurt your fingers the longer you use it so I opted to buy and use Staedtler for my college drawing classes. My friend Jonathan and I bought our Staedtler College sets at Pecton Mercantile in New Manila. Along with the purchase, they gave us free T-Shirts. So, I searched Ebay and found the Tikky sold in black. I quickly made my purchase for only $3.00. Since its made for drafting, the Tikky had a fixed sleeve. The grip had the familiar wave design and as I expected, it wasn't very comfortable for longer writing since I am a heavy gripper. Like most of drafting MP's, the metal cap is clicked to advance the lead and also hides the small eraser underneath. However, I must say that this is one classic pencil that is a must have in any MP collection.
