Query: Not Very Durable

This pen is not very durable. I have owned two in the last about six months and both broke at the cap. After the first one broke soon after I started using it I thought perhaps it was just a fluke so I bought another one. That one broke in the same place. There is nothing unusual about how I use or store the pen (in fact I keep it in an elastic band with my tablet).
