          No-Foil Flat Back Rainbow Crystals for NeoPixel LEDs - 100 pack - SS16 PRODUCT ID: 4044 Bedazzle your board with these No-Foil Flat Back SS16 Rainbow Crystals. They're a lot like the crystals you see decorating clothes, bags and phones. But unlike most crystals you can buy these have no reflective foil on the back, which means they let light shine through and sparkle. This makes them not-so-great for decorating bland or boring things, but really great for gluing onto LEDs and NeoPixels! Jazz up even more shimmer and sparkle to the Circuit Playground Express, or maybe you have an e-textiles wearables project that needs a little extra flair? Use a small dab of glue to attach right over the opening of a NeoPixel, for an extra bling. Note that the foil is what usually adds a lot of shimmer, and since its gone you won't get that extra glam. Comes in a pack of 100, so it's OK if you drop some on the floor. TECHNICAL DETAILS  Single crystal: 3.7 x 1.3mm                                                                                  https://www.adafruit.com/product/4044/1‐23‐19
