The #18 cork stopper will fit a hole that measures 34.5mm or roughly 1 3/8" & is suitable for bottles or jars. Buy just one for $1.30 or save 30% when you buy 100 or more.


The #18 tapered cork stopper is our largest and measures 38x38x30mm (1.5x1.5x1.25" height/top/bottom) and fits our largest tube, the 38x200mm. The #18 cork bung also fits the 1000ml erlenmeyer & boiling lab chemistry flasks & may fit small glass jars and bottles but check the size first before ordering.

Corks were correct size and quantity and well made as I had to make two 9mm holes through ends. Material held together as I expected and did not break off.

They corks are solid and not a glued aggregate. It sounds like that was a benefit to you which is great.
