Instructions
For optimal hold, please follow these instructions. To remove the gasket: gently pinch, rotate, and pull. Sliding a fingernail under the gasket may also help.
Then, slide the stem in the hole, making sure the bristles are facing down and that the stabilizer dot it closer to the spoon end.
Then flip the gasket over and slot it around the stem, making sure that the wide end of the gasket is on top and that the whole gasket makes its way under the stem end.
To remove for replacement: simply pull down hard on the brush.
