Custom shaped microfoil balloons can be made to your specific size and shape requirements. To create these custom shapes requires the manufacture of a metal die that can be used to cut your custom shape. Dies are an expensive part of the custom balloon process that cannot be avoided. Dies start at $5,000 but can be more depending on size and complexity. In addition lead time for custom shapes is about 14 weeks to allow enough time to make dies, plates and then to produce the balloons.
