We love using these- they're easy to pop on and off and give a tight seal against ants or fruit flies, plus they're washable. More sustainable than tossing out hundreds of coffee filters or paper towels, and has a perfect snug fit.

    I love them!

    These are terrific, I don't have to fumble with coffee filters and rubber bands any more!

    Absolutely perfect

    Absolutely perfect. We're using these to cover oils that we're sun-infusing with dried herbs -- they need to breath, but be protected from dust and insects. Thanks so much for making them available!


    So beautiful and useful. All is nicer after I got them!
