I have two children now and used an amber necklace with my first, it seems to make a difference so I got this one for my second baby. I love that it comes as raw amber and with color options, the light brown tone is beautiful!I didn’t realize it’s a pop release clasp but it stays on well, doesn’t just fall off but definitely releases with a little effort. The one I got for my first screws to connect and I’ve never had any issues with that so I like that kind but the pop release seems great too. It fits just right and now I’m tempted to get myself a bigger one in the multi color to match my girls!
