Golden Artist Colors has created the GRIPR Tube opener for those stubborn paint caps. Made of strong and flexible ABS plastic, this paint tool has 4 cap sizes and allows artists to squeeze, twist and remove any stuck caps. Works with both old and new 2 and 5 ounce Golden tube designs, as well as similar sized caps. Also works on Williamsburg Oil tubes, QoR watercolor tubes, and any other brands that have similar sized caps.
