Ah, so this is what they mean by party favours. It's not contraband after all, but rather, crepe paper. That explains the unpleasantness at my niece's birthday party - an honest mistake.
What there is no mistaking, however, is that Canuck Amusements has a massive selection of party decorations. No matter the theme they've got you covered (Weddings, Anniversaries, Bachelorette parties, baby showers, etc.) Besides their huge assortment of party accessories they also offer customized trophies and engraving, balloons, darts and accessories, bingo supplies, costumes, toys and trinkets and more.
