These sets of “Party Loot Bags” use Cyrus Highsmith’s Eggwhite (2000). The designs probably date from around the mid-2000s, when Expression Factory (a brand of Regent House) used the typeface on their website, too. The domain is no longer in use since 2015.
“It’s Party Time!” additionally features Curlz by Carl Crossgrove and Steve Matteson.
