WE HAVE SOME ANSWERS!

FREQUENTLY ASKED QUESTIONS

How long does the battery last?

How durable are the fibers?

The fiber optics used for this product (Standard version) are high-grade 0.75mm end glow fiber optic cables and they are very durable and will withstand pretty much any movement you make in your costume.
We have been sourcing fiber optics from the same manufacturer for over 10 years now and our fiber optic products are widely considered the most durable on the market.
Sparkle Fibers show tiny twinkling lights along the length of the end glow fibers. They are more prone to breaking. Please be gentle with the Sparkle Fiber version of the Fiber Optic Costume Kit to avoid unwanted fiber breakage.
