WingCap (Adaptor Cap)

Finally, it's here! The WingCap lets you use your favorite caps on your local hardware paint brands, like Rustoleum, American Accent and many more.

This adaptor cap is for use on cans with a "male" valve system, with a "male" cap (like all those German caps and NY caps we are selling in the online store). For a fat cap use, we recommend the NY Fats. Combo Packs are available here.

Easy on the fingers with the Wings, reusable many times, this is a must-have tool for all writers. Do not clean with acetone or paint thinner.

BONUS USE: try your WingCap WITHOUT any tips, simply by pressing down the Wings... surprise, surprise!

    Amazing adapter cap. Easy on and off with the wing tabs. Makes painting with rustos a bit more manageable. Well worth it.

    I always avoided rustos before these came out. Not I can finally use my beloved Harbor Blue rusto.
