Neon Tumblers Fire up the grill, gather up the friends and take the party outside. In sundrenched shades of neon, these unbreakable food-grade Polycarp tumblers are fun and festive, born for chilled whites, pitchers of sangria, splashes of lemonade and just the thing for ices and sherbets too. Dishwasher and microwave safe. Set of 4 neon bright as shown.
