We were very happy with these cups. We used them for my daughter's Halloween party where it was important to see the color of the drink and the boba pearls. They were perfect to see the drink, yet also still sturdy and durable enough for a group of teens. The size was just right too. We love that they are compostable. I would definitely buy these cups again and again.I have flat lids at home (that are also composable), and thinking that single use cups and flat lids are sized universally, I purchased these cups.I didn't see any description regarding size (i.e. dimension of cup), other than volume capacity (and yes, I checked).*****The mouth of the cup is TOO SMALL for my lids. So essentially, unless I purchase these company's lids (which come in a 1000ct) I can't use these as to-go cups w.o risking my drinks making a messThe actual cup serves its purpose of holding liquids and being sturdy (hence more than one star) but since the product cannot be used to its "fullest potential" I can't give more than 2This is our first trial of PLA cups, and because these have no printing they were less expensive than other brands. They are clear and strong and the lids we bought snap on well and are secure. Will buy them again.I am giving two stars because the cups themselves seem sturdy, not brittle and feel similar to the non-compostable types. Our disappointment came upon receiving our case of 1000 and counting between 47-49 cups in each sleeve instead of the full 50. Each sleeve was fully sealed so it seems the manufacturer might be counting on customers not noticing that they are shorting the case.Good quality large cups for the moneyAll the convenience - non of the guilt. Great product.Lids cracked- so when you have whipped cream or want to fill the cup with extra product it’s a risk.I had two personally and some of my customers also experienced cracking. Great price- just not good quality.Very flimsy not a good productBeware lids did not fit either could not hold the coffee with put the cup caving in
