Most blow-mold pumpkins are made from hard molded plastics. Common materials listed include polyester and polypropylene, generally described as rigid plastic construction.
Blow-mold pumpkins are available with two main power options: plug-in (electric) and battery-powered. Some models plug into a standard outlet, while others run on batteries.
Blow-mold pumpkins are offered as either hanging or freestanding decorations. Hanging or wall-mounted silhouettes usually include a top hook, while freestanding pieces are intended for tabletops, mantels, shelves, or windowsills.
Battery-powered blow-mold pumpkins in this set use AA and button-cell batteries. Examples include models that take 3 AA, 2 AA, or 3 LR44 (button-cell) batteries.
Many blow-mold pumpkins are light-up designs with interior LED lighting or LED bulbs. Descriptions note colored or soft glows, and at least one model offers multiple light settings.
