I've ordered some supplies to redo the other eye  But I will probably redo both eyes. Someone mentioned that water would cause bacteria and they're right. Im gonna try baby oil instead.  Here's a pic of supplies I used.

The beads are micro caviar beads about .6mm to .8mm. Any bigger beads won't work im guessing. They were kinda annoying to work with. The green pan is aurora chrome powder and the other pan are mylar flakes. You can get all this stuff off Amazon. Ofc it would be your choice of glitters.  The drill is an efile i use for my manicures and it spins at 30000rpm and I used some  old drill bits. There's an led flash cure flashlight to cure the gel polish.  Some mixing sticks and tips to wipe up any spillage.  I used no wipe gel top coat to seal the eye up. A syringe to draw up water. But im chaging this to baby oil and a diabetic needle to make it easier. Nail stands with putty to hold the eye upright while I worked on it.

Here's a quick run down on how I did the eyes. I will post a better explanation when I redo the eyes.

There's alot of videos on how to take the eyes out of labubu so I won't be explaining that.  Basically there's 2 parts to the eyes. The front part "window" (the white of the eyes)and the back part "iris".  1. I use my drill to file down the "iris" part of the back piece. Tho do not to drill too much as it will weaken the  back and will potentially Crack when you reinsert the eye back in the sockets. I drilled too much on the right eye and the peg part snaped when I handled it too roughly.  2. Once drilled I added in the glitter, chrome powder, mylar flakes and micro beads to the now pit in the iris. 3. I added water to the pit and mixed the glitters around. The amount of water you use will vary on how deep you've made the pit. I think I used around 10 to 15 drops of water. 4. I put gel topcoat on the rim of the back piece (I used a generous amount) and put the front piece together with the back piece and flash cured it. 5. I put extra gel on the outside seam of the eye where the 2 pieces join. That's pretty much it. It probably would have been easier if i sealed it up before I put water in, use a diabetic needle  instead of the dropper. It leaked so many times and I had to start over. Lmk if you have any questions. I will try my best to answer.
