Lava Ledges

Usually I make sure my two chins have two lava ledges at all times, but they've already chewed through one and broke it off the mount (now it's just a chunk on the cage floor) and about halfway chewed through the second one. During these Coronavirus times, I'm not sure if I'll be able to find more lava ledges for them that aren't overpriced. I tried a brand other than Kaytee (I know, I know, terrible brand, but their lava ledges are decent) and it was pretty good, but I found it in a pet...
