Switching out tank tops to a solid one? Need advice!

[HermitCrabsRCute]

So I have a 10 gallon critter cage by Zilla for my hermit crabs. I now realize the mesh top won’t keep the heat and humidity in. The top slides in and locks, so I don’t know what other solid top
I could put over it to keep it warm/what I could buy?

If you can't enclose the lid in saran wrap because it slides, you could also tape plastic ziplock bags all over the top. Porous materials like towels or blankets will absorb moisture instead of holding it in.
