TWSBI Vac Mini (Smoke)
The TWSBI Vac Mini is a shortened ‘pocket’ version of their longer Vac 700 model. The latter model has been copied as the Wing Sung 3013/Paili 013 (qv)
As the name implies, this is a vacuum filler. As the body is quite short, many writers would want to ‘post’ the cap to provide a comfortable length and to assist this the end of the body is threaded so that the cap can be securely attached.
