5 Red Clear Heart Acrylic Votive Tea Light Candle Holders

5 red weighted, heart-shaped votive or tea light candleholders. each heart measures approximately 3” x 3” and 1.25 inches deep. I believe these are acrylic and not glass but I can’t be sure. They don’t seem particularly fragile, but I don’t know if they’re breakable. Please see for scale. The votive candle is for reference and not included in the purchase.
