Introducing the Spectra Ad Refill in Gray Color Family, the ultimate solution for extending the life of your beloved Ad Marker. Each refill bottle is designed to refill your marker 8-10 times, providing unparalleled value and convenience. The ergonomic shape of the bottle features graduated markings to indicate the volume of the refill in milliliters, ensuring you're always aware of how much you're filling your marker.

The innovative design of the refill bottle makes it easy to use and refill your marker. Simply remove the nib of your marker, insert the refill nozzle, and gently squeeze the bottle to fill it to the recommended maximum of three lines (3ml). The easy-pour spout is specifically designed to fit into the marker, making the refill process quick and mess-free.

But that's not all - the alcohol ink refills can also be used as a standalone product. The spout doubles as a dropper, allowing you to apply the ink directly to paper or pour it into a container to use with a brush. You can also mix and match with other Spectra AD Alcohol ink refill colors or the Blender to create unique shades and hues.

To ensure a seamless refill process, follow these simple steps: match the marker and refill number, remove the nib, insert the refill nozzle, and gently squeeze the bottle. Fill to the recommended maximum, and then re-insert the nib. Your marker is now refilled and ready to use! For optimal results, store your marker horizontally.

As an added assurance, the Spectra Ad Refill meets the highest standards of quality and safety. It carries the esteemed AP seal, conforming to ASTM D-4236, ensuring a safe and healthy creative experience.

The Spectra Ad Refill in Gray Color Family is an indispensable accessory for any artist, designer, or crafty individual who relies on their Ad Marker. With its remarkable refill capacity, ergonomic design, and versatile uses, this product is a must-have for anyone looking to unlock their full creative potential.
