Sure! Here is the link to the sand I've been using

I hope it's not a problem if they ingest sand! Shouldn't it go through their gizzard?
I have been ordering play sand online from Home Depot for curbside pick up, it's very convenient! There is no way I can lift a 50lb bag of sand in the store. Play sand works for us since it's dry! I used to get washed sand and it was a pain in the neck to dry the sand.
