Review on 🌿 Green Grass Design Disposable Hot Paper Cup - Eco-friendly, 100% Biodegradable & Compostable - 8 oz, 50 Count (Color: Green) by Tony Bennett

I bought these as a more sustainable option and overall they are surprisingly durable. The base does seem to sag a bit when pouring coffee (but doesn't leak) and you definitely need sleeves when the drink is hot, but the lids close easily and the seams show no signs of coffee seeping after an hour+. I've been using a cup a day for a week and haven't had a single leak yet. Another positive point is that the lids do not transfer heat well. Other products were so thin that when hot coffee hits the lid, it heats up so quickly it burns my lips. Not so with these. Note: I have not stuffed or microwaved, so I cannot speak to the product's ability to pass any of the tests.
