Edible Black Dual Tipped Markers. We are excited to offer the finest tip pen on the edible market at this time. The fine tip is .3mm and there’s also a larger tip on the other end, both tips are pictured. Black Markers are made with FDA Approved edible ink. These are great for both fine details and larger projects too because of the dual tip. The markers are standard size, about about 6.5″ long. Great for writing or drawing on dried royal icing, fondant, macarons and more. Not recommended for chocolate. Buy in bulk to save!
