DOITOOL Coffee Mug Lid 2Pcs Stainless Steel Cup Cover, Universal Coffee Mug Cover Lids for Ceramic Mugs & Drinking Glass, Tea Cup Cap for Steeping, Home Office Desk & Camping (3.9 Inch)

Works ok. Could be wider for larger cups.

Good quality covers 4-inch mug perfectly - still useful for smaller cups.

Lids are too large for my regular size cups. A bit disappointing.

It's the top of most small to medium sized coffee cups, but my large ones it does not

The covers came with a sticker on under side of lid that was nearly impossible to get the glue off. I tried everything and finally after hour of messing with it I think they are ok to use. Ad said they are food grade stainless but are they really? Very light. Wondering if the nob will overheat. Well, they will work just can't recommend.

They appear to be stainless steel. They work as intended. Seem to be well made.

Its a little larger than a standard coffee/tea cup. Material is good. Maybe I can use it with a standard rice bowl.

Do the job, only thing is they get hot to the touch after the tea steeps
