The configurator is self-explanatory. It guides you starting at the tip along the dart. For all four elements you have different choices in shape, color, size, weight, etc. For questions about the individual elements you can use the info button at the bottom of the selection field. It should not leave any question unanswered. If you do, please send us an email with your question to support@mydartpfeil.com. We will answer you immediately.
