Bizarrely, I can answer this rather extensively, so here goes!
I used to buy these
and they were very similar to the ones in the recovery bracelets from the RYL. The link is to an item by the same seller that I bought from, although I always got 6mm or 8mm so I'm not sure if 4mm will perhaps be too small, but if you just search for cats eye beads you'll get tons from other sellers too.
The bracelets were orange and white I think. The bracelets that I can remember are:
SH awareness = all orange
SH recovery = alternating orange and white
1 month free = one quarter white (all together) and the rest orange
3 months free(?) = half white (all together) half orange
6 months free(?) = three quarters white and the rest orange
1 year free = one orange bead and the rest white
free = all white
I was slightly winging it there, but I hope that that is vaguely right! I think there were some ED recovery bracelets in the shop too, but the small size was sold out every time I looked (lol) so I don't know what they looked like.
I hope that's helpful :)
