PandaHall 200pcs Mini Glass Orbs, 4 Size Crystal Craft Ball for UV Resin Dice Pendant Charms Earring Making (12mm, 14mm, 16mm, 18mm)

I am so happy I got these. I started making liquid core dice with these and they work fantastically. They stand up to the pressure pot when full of liquid and covered in epoxy resin. I used 3d printer resin to seal the hole but I need to get some standard UV resin cause the 3d printer stuff yellows like crazy and it's really obvious inside the dice. But yeah, none of these were broken when I received them. They are all shaped well and have similar sized openings. I'm very pleased with them

Got these to make liquid core dice and they're perfect! Arrived very well packaged and none were broken. I use a bit of UV resin or hot glue to seal the top after pipetting in water & inserting glitter and/or mica. Not sure how they'd last if put in alone, but when they are surrounded by resin in my dice moulds and under pressure (approx. 46 psi), they are fine! No cracking or other fractures.

They arrived early and only 1 of the bulbs was broken. None of them are perfect sphere shapes, all of them look a bit squished and there's definitely a little extra glass that pooled at one end like other buyers have mentioned.I bought these to make liquid core dice, so I'll wait until I've made my first set before i make further judgments.

I needed some sort of clear spheres to make glowing eyes for a giant animatronic spider. I was able to superglue these to the tips of standard 5mm LEDs and they worked great! You could probably make a standard 3 mm LED fit inside the larger glass spheres As I needed them to be shiny black when the LEDs were not lit, I sprayed them with automotive brake light tinting spray achieving the desired effect.It's possible I will need more glowing red eyes for future projects and would definitely order more.

So these are so very cool. I'm so happy I ordered them as I had all the standard fears but they really are what's pictured. Excellent product will use again.

They are as described, i was not disappointed and had NO black rings as other reviewers mentioned.

I didn't realize it didn't come with the metal caps that other orbs came with and some of them were broken or cracked otherwise I would give 5 stars

These seem to be good quality. I was worried when other reviews said the rims were burned on some, but i did not have any burnt ones nor any broken ones.
