Using these 8mm plastic bevel LED holders is super easy. First, take your 8mm LED and carefully slide it through the opening of the holder. You'll hear a snap sound when it's properly in place. Make sure you use the right - sized holder for your LED project. If you need a different size, we have 10mm, 5mm, and 3mm options available. Remember, these packs come without LEDs, so you'll need to get your own. To keep the holders in good condition, avoid bending them too much or exposing them to extreme heat. If they get dirty, you can gently wipe them with a dry cloth. That's all there is to it! Enjoy your LED projects with these handy holders.
