Just looked at the pic's - sorry mate will not bleach white
as for dying - it might but it has to be a darker colour and if it doesn't have any nylon in it when it was made it will not take - if it does it might dye ok
it's never easy to tell till it's in yer hand
is the plastic hard or soft / you don't show how it un-clips
if you were to dye it what colour are you looking to go ?
cheers B
