The paper is very thin and hot beverages have not fared very good especially if left in the cup for awhile Disappointing and I will not purchase again.
These cups are real heavy paper so sturdy for a hot cup of coffee or a cold cup of water and ice. Plus they are compostable. The 10 oz size is perfect for our work station coffee bar.
Sturdy cups, stacks and store easily, 8 oz a good size to manage coffee consumption in a large church on Sunday mornings so everyone gets some. Keeps drink warm & no scary forever chem.
