Tapa de plástico Harder y Steenbeck.

Bought this to reach $10 spent on an order. I had been suggested it prior by a youtuber and exspected it to be somewhat more special inside then outward appearance implied. In truth you could he using a marker cap or something and I found it to be very silly. Im only keeping it because its yellow.

Works good for back flushing, both for mixing paint in cup, and on cleanup, the only reason I gave it 4 stars is it not as well made as H&S other products.
