I understand your concerns. I wish I could pre-install the clips for everyone, however that would require me to limit the number of colors offered or would increase the cost due to additional shipping and handling fees. On demand additive manufacture offers numerous benefits and enables low volume products such are these to be supplied to consumers but it also has its downsides. I assure you that the vast majority of customers have no difficulty installing the clip. If you do have difficulty please let me know so we can find a solution. Please let me know if there is anything else I can help you with.
