To my knowledge Jack is no longer in Belize but you can purchase some of his work at the Sea Fan gift shop on Middle Street in San Pedro, or in the art gallery in the Tourist Village in Belize City.
The shop you buy from will ususally have a preferred method of shipping depending on the product, size and weight. Our goods tend to be light but sometimes large in size and we send them as insured international parcel post. They are breakable so we wrap them well, we have never had a problem with damage (so far - touch wood!)and they arrive in about 10-14 days to the US. About another week to Europe.
