This is a set of two used Sheaffer TRZ Model 70 pens. According to the catalog, the surface is 23K gold plated. This model was part of the lineup from the 1970s to the 80s and was later discontinued. One of the two pens is a novelty item, and the clip design is slightly different from the standard model, but the sticker indicates it is also a TRZ Model 70. Both pens have dried ink and will need to be refilled for writing. These are vintage used items, so they have corresponding scratches, scuffs, and stains. Please consider this before purchasing. No claims, no returns, and no cancellations.
