I could have them out on the market in about 2-3 months time via injection molding. I can have a mold made and the initial run made in about that time. May take longer if the mold needs revisions however this typically doesn't need to happen for such simple molds. If you would be willing to try out the sample and provide me feedback about any changes needed it would be appreciated. Also my price point could be lower than $5.00 a shell.
