The drawbacks are substantially the same of the ''match-stick filler'', soothed from the fact that a coin is an object generally more common and it is not necessary to be smokers. The larger size of the slit on the body, however, made the pen less elegant and more prone to problems. Often the slit is identifiable with respect to the case of a toggle pen in which the latter has been lost, by the presence of an additional round central hole slightly larger than those of the slit. | The drawbacks are substantially the same of the ''match-stick filler'', soothed from the fact that a coin is an object generally more common and it is not necessary to be smokers.
