My Canadian Threadless

These are the 6 intact ones I've found in the wild since 2011. The first 3 on the left were all found within a few km of each other.

 

All my best insulators have a small sticker on the backside revealing the location where they were found along with the date.

 

3 blue aqua with milk CD 742s, light minty green aqua 742, cornflower blue M.T.Co 742 and teal green 742.3.
