Available sizes of stemming plugs

VARI-STEM -- Size Chart
This size chart is only a guide.
In many cases, undersized plugs prove effective, especially in cold weather.
In cold weather the plugs do stiffen up. We recommend trying to keep the plugs in a warm environment (i.e., truck cab) prior to use, in order to keep them flexible. We can provide a low temperature formula, if needed.
