We cannot 100% guarantee that these will be shipped out by Christmas, but it's very likely we'll have access to more ebony wood next week, and we'll do our best to make as many as we can before the end of the Kickstarter Project.
Beyond the first 50 that are guaranteed for Christmas, we'll be fulfilling Ebony Muddlers in the order they are pledged for. That could be by Christmas, or it could be January. Once we run out of locally available ebony, the next batch will arrive from Cameroon in a few months, so we'd fulfill the rest of the muddlers late Spring. So if you want to add a +1 Muddler to your pledge, or if you want to upgrade to Ebony from Maple, you can do that now! Check out the FAQ at the bottom of the project page for more.
