A medium to large size fountain pen with the option of a standard or Solid Gold nib. The Bolivia is hand made by Sigma and the large size medium stroke nib is a treat to use. Available also is a Solid 14kt. Gold nib in medium. Presented in a velvet-lined case with Full Sigma Warranty there is a choice of colours with the option of a red acrylic barrel with black cap. This is a good option particularly if you require a name engraving for a special gift or presentation.
