Borco Vinyl Board Cover BORCO is the ultimate vinyl drawing board cover. It is a durable several layer cross-bonded material with the ability to self-heal surface cuts, compass point holes and pencil impressions. The core is four layers of rubber film with a hard plastic surface on the top and bottom. This eliminates the need for excessive pencil pressure and does away with "ghost lines" on tracings. Double sided, one side green, the other ivory and is non-glare.\n\n
