Craftdady100pcs 10mm Half Round Crystal Glass Mood Cabochons Temperature Sensing Color Changing Flat Back Cabochon Bead Charms for Pendent Jewelry Craft Making

These beads are supposed to change color with your mood but they don't! They start out black and may change to a dark blue, no other colors as advertised. Don't waste your money. I've been trying to return these beads for 1 week. We have no UPS STORE so the come and pick up but didn't for 3 days. I'm still waiting for a voucher or refund. My customers need their replacement jewelry made with these junk beads!!!

I felt it was a good value for the item, but I'm a little disappointed that these cabochons dont have flat backs. they are slightly domed. So when making rings, they are fairly bulky

So very subtle on the color change. These aren’t big enough to do much craft with and not worth it for a ring since the color change is lacking.

8mm cabs, not flat on the back. I did use to make some fun earrings. Jules Jewelry Box on Etsy.

I'm so disappointed in these. The backs are not flat causing them to not adhere to the settings at all

I like that these are actually glass and not made of resin. They change colors really well.

Nice beads but they are not flat backed.

No color change... Did not work

I make earrings and thought that these would be perfect. However the backs are just slightly rounded so unless you have some serious glue that you trust, not ideal for that purpose. They are quite pretty but they just stay at the constant blueish colour no matter the temperature. I still gave it three stars because they are pretty and just don't have to advertise as mood beads. Can still be used for crafting.

I put 4 of these in my hand and they all turned exactly the same colour, I am using them for jewellery making
