|Conway Stewart and Eversharp glass tubes - note the square leads.|
|Various metal tubes and containers|
|Special leads in heavy duty metal containers|

Moving on we have a variety of wooden tubes and containers
I really like these slotted wooden type holders.
|Scripto's in wooden holders|
|0.036" = 0.9mm = 'Extra Thin Lead'|
|Wooden tubes for politicians?|
and of course cardboard tubes
|Gonna get that Road Runner|
