The small pastel-colored candies, with sayings like "Be Mine," "XOXO," "Crazy 4 U," "Soul Mate," "Me & You," "Sweet Pea" and "Cutie Pie" will not be sold this year due to Necco's factories closing.

"We wish we could have Sweethearts out for the 2019 Valentine season, but it's just not possible," Kirk Vashaw, Spangler chairmen and CEO, said in a statement to ABC News. "We are committed to making sure these brands meet consumer expectations when they re-enter the market. Doing it right takes time."
