Blue treat boxes and containers are made of paper/cardstock, various plastics (including recycled PET), and stoneware ceramics.
Most cardstock favor boxes ship flat and require simple assembly—typically folding or interlocking tabs to form the box and top.
Common protective features include secure lids or snap-tops, portable handles, sturdy cardstock or rigid plastic construction, and lids or seals for enclosed storage; some plastic options are also BPA-free.
Some favor box kits include coordinating satin ribbon and gift tags; several listings explicitly note ribbons and tags as included kit components.
