Customise your QBone Dual with a custom PETG or resin handle!

When ordering with a QBone, your choice will be substituted for the default black PETG handle, and riveted to your QBone.

If you are ordering more than one handle along with your QBone order, please specify in the shopping cart "Special Instructions for Seller" box which colour you would like riveted to your QBone.

Perfect for connecting to your CRT terminal!
