Enduras are exceptionally well made pens. The caps and bodies are made out of thick durable materials that have held up well to the test of time. The red and the black rubber models were available both in traditional crescent fillers and in lever fillers. I have never seen a wood grain pen or a plastic model in the crescent filler but they may exist. The locking ring normally matches the pen color on crescent fillers. They were available in a number of beautiful colors and a size for everyone. Colors for hard rubber are red, black, and mahogany. Plastic pens come in black, red, verde green, black & pearl, lapis blue, black & bronze, and imperial purple & yellow. The nibs for these pens are normally marked endura. While other nibs may have been fitted in the pens only the Endura nibs are considered to be correct.

Enduras have problems with their pocket clips. Clips are missing on many pens due to the deterioration of the spring steel clip that holds it on. It corrodes and breaks and the clip is lost. They can be replaced but and exact replacement is needed. Plating wear is common on the pocket clips, Cap bands and on the edges of the lever. The wear is common on the edges of the clip and tends to wear away detail in the inscription. These parts can be replated if necessary. The most common serious defect is in the lever pins. They are bad about developing cracks in the plastic or rubber and pulling out. Repairs to this problem are difficult and not overly satisfactory. All of the rubber models have typical cracks in the cap lips. Again repairs to rubber are mainly cosmetic and not very durable. Oxidization is common and effects the color and value of these pens. Enduras are known for weak imprints. Conklin had trouble determining the correct pressure for applying them so many are almost nonexistent. There is an unusual trait to some Endura nibs. They seem to be made from poorly mixed gold and they tone and corrode badly. Polishing these nibs can completely remove the inscription and destroy their serviceability.
