Alternative lid for refillable mugs?

[Meglen]

I have never had one but was wondering if any other lids would fit. I would love a more "secure" top. Any lids laying around the house tend to fit this thing? TYIA

What do you mean by a more secure top? The tops that are used fit very tight and at times they are very difficult to get off so i am a bit confused as to what you mean

More secure? I can hardly get them on and off now!

I think that they might be looking for a lid that doesn't leak when you tip over the refillable mug. The current lids are not leak proof.

Yes this ! Sorry for not explaining better. We normally bring a few water bottles to fill up during the day but if I can find better tops than they can be multi use.
