UV Gel Core Fritz 15mm from Flybox features added new mobile-flex UV fibres to add a subtle UV sparkle to the material. Built on Flybox’s revolutionary ‘Gel-Core’ the material is incredibly easy to work with and won’t split or fray from the core. There are many fritz’s out there, but only Flybox manufactures Gel-Core – so if it’s not got their label on it, it’s not the real thing! Imported from the UK
