Narrative: I made these to diagram my notes from 2003 - 2007. They consist of marker, glue, pen, different types of paper, printer ink, and paint.

The marker bodies, caps, and plugs are formed from plastic resin. The marker reservoirs are formed from polyester. Powder and water are used to form the felt writing tip. In addition, felt-tipped pens require ink, and the pigments and synthetic substances used to make it. Toluol and xylol are synthetics used as solvents in dye as well as chemicals such as cyclic alkylene carbonates. Conventional additives, such as nonylphenylpolyglycol ether, alkylpoly-glycol ether, fatty acid polyglycol ester, or fatty alcohol ethoxalates, and preservatives, such as ortho-phenolphenyl and its sodium salt, ortho-hydroxydiphenyl, or 6-acetoxy-2,4-dimethhyl-m-dioxane, may also be added to the mixture. To make the body of the marker, plastic resin is injection-molded into a pen's body. Pen caps and plugs are formed in the same manner as the barrel.  The nib, or tip, of the marker is made from powder mixed with water, molded, and baked into its pointed or flat form. Using one machine for all the following functions, an assembler then places a polyester cylinder inside the marker barrel to form a reservoir for the ink, fills the reservoir with ink, and inserts the nib at the bottom and the cap at the top.

The points of most ballpoint pens are made out of brass, which is an alloy of copper and zinc. Oleic acid, castor oil, or a sulfonamide plasticizer are also used. The markers bodies, caps, and plugs are formed from plastic resin. The marker reservoirs are formed from polyester. Powder and water are used to form the felt writing tip. In addition, markers require ink, and the pigments and synthetic substances used to make it. To make the body of the marker, plastic resin is injection-molded into a marker body. Injection molding involves heating plastic resin, into a molten state and forcing (injecting) it into a mold of the desired shape, then allowing it to cool and harden. Marker caps and plugs are formed in the same manner as the barrel.  The nib, or tip, of the marker is made from powder mixed with water, molded, and baked into its pointed or flat form. Using one machine for all the following functions, an assembler then places a polyester cylinder inside the marker barrel to form a reservoir for the ink, fills the reservoir with ink, and inserts the nib at the bottom and the cap at the top. The markers are then placed into color assortment and packaged for retail marketing.
