What’s the difference of me using a cheep plastic cup and lid from Costco or Sam’s club? Or even a glad-ware container? How much am I really needing to touch up? Also pints of paint last in the can for a while. You can easily pop the lid, stir and use a disposable foam brush to touch up where needed, then reseal, toss the brush and use again another day. I can easily see Khabby doing a video about this product. Lol
