## Customer Reviews

### ⭐⭐⭐⭐⭐ Briliant color, good quality
*by M***N on September 24, 2024*

The color is lovely...the size is perfect for embellishing shoes, which is what we used them for. It is a part of a costume for a video.

### ⭐⭐⭐⭐⭐ Great costume addition
*by A***R on December 21, 2024*

Bought to enhance daughter's costume. Unsure what anime character she dressed as, but apparently the gems were perfect and I'm now the best dad ever. So there.

### ⭐⭐⭐⭐⭐ So pretty!
*by A***M on March 2, 2025*

They look perfect. Color is accurate to the photos, and they're very sparkly!
