Sugar Skulls look great decorated with these bright neon gel colors to tint your royal icing - Muy Mexicano! These are more "liquidy" squeeze bottles than the concentrated pastes colors so they are a bit easier to use; but if you're making big batches of Royal Icing, they won't color as much icing as the jars of paste color. Both types have their advantages. These bright colors pair wonderfully with the colored tin foil assortment pack. Neon color bottles are 0.75 fluid oz. These colors can be used year for other cake decorating projects.
