Yes

It is to open the bullet cover

I bought this cup. The advantage is that its silicone feels very good, very skin-friendly, and the texture of the white cup body is also very good. The disadvantage is that when the cup is placed on the table top and pressed with one hand, the lid will bounce up and hit the hand while the cup body will pour down. Another is that the drinking port is a little far from the edge of the cup. If the water is too urgent, the water will spill out

Thank you for your feedback ~ ~ will improve!!!

However, the whole cup body is very comfortable in terms of shape and material
