Use this replacement 3/8" pen tube if you have damaged the pen tubes that came with your pen kit.
These pen tubes are 10" (approx 25cm) long and should be cut to the correct length using a fine saw.
Please note, the tube fits a 3/8" drilled hole. The tube diameter is a bit smaller than 3/8" to fit the drilled hole and have space for a glue layer.
After cutting, they should be squared using a barrel trimming set.
