Rarity & Significance
High significance for collectors attempting to repair or complete a broken MattyCollector Proton Pack. Since these packs are out of production and prone to 'bumper snap,' individual original parts are highly sought after in the secondary 'part-out' market.
Special Features
Ribbed 'shock mount' bellows design accurate to the hero props from the 1984 film; pre-drilled mounting holes for attachment to the main shell.
Notable Variations
The orange bellows on the Mattel version are made of a stiffer plastic compared to the rubber versions used in high-end fan-made props or the official HasLab version. This specific sculpt is unique to the Mattel 2011 tooling.
