Design pro here! I used these reflective mirrored silver discs to bring light to a royal blue (team color, had to use) centerpiece for a church luncheon (used recyclable faux greenery, no budget) in the middle of winter (no blue flowers, used deconstructed faux). And I LOVE THEM!!!!!!!!! They are FABULOUS!- Each disc is about the size of a dime.- They are made of I think mylar? Like a foil-coated cellophane. They are thin, flexible and not rigid.- If any clump together in their baggie, just RUB BETWEEN YOUR FINGERS to separate the clump. They are perfectly die cut so they have no rough edges and the coating is 100 percent cured so no transferring -- any clumped discs separate very, very, VERY easily.- I add these as a final layer of decor on centerpieces to reflect the light and add bling to the tabletop.- I also like to pair them with strewn "diamonds" like faux beach glass for a final layer of detail and to give the mirrored discs more things to bounce light off.- When the room is lit by candlelight, I go heavy on the bling; for daytime, more conservative events (church luncheons!), just enough to make each centerpiece sparkle.- These mirrored discs are big enough to not be annoying to clean up (hello confetti haha).- LOVE!! I am adding these permanently to my table decorating repertoire.
