Need a bit of help finding a glass dish for a feeding dish/Question regarding a substitute

[Gentlemangorath]

So I've decided I want to leave a feeding dish for the Gray Tree Froglets when they're moved into their new home, to avoid them having to hunt the crickets down in a large environment (compared to them). The issue I'm having is that the dollar stores I've been to do not seem to have the cooking dishes I hear people use, but only slightly shallow ash trays. I've picked one of these up, the deepest I feel I could find, and I tossed some crickets in to see how it worked. It seemed to work, but I think one of the crickets may have managed to escape, probably from jumping out (It's only about half an inch deep). So my two questions are; 1) Where can I go to get a good dish for a feeding dish? So far I've checked the local Dollar General, Dollar Tree, and Walmart, but all three only had the shallow ash trays, but no luck with what I'm looking for. And question two; would the ash tray suffice or is it simply too shallow? The crickets certainly weren't able to climb the sides, so that's a plus, but on the otherhand one of them may have bounced out of there. I'm also considering taking a picture and linking it here with a lighter next to it so that people can see the size in relation to another object.

I've seen them in kitchen section at local Walmart. Can also check at Michael's, Target, and other large department stores. Online, Amazon sells several kinds under "small glass bowls" too !

I used to use a Pyrex baking bowl. I think when I bought them a few years ago they were 3 for $5-10. They came with lids and were pretty small but had a flat bottom. I found a link for Walmart if you're interested:

Pyrex 6-piece Storage Plus Value Pack, 3 each - 2 cup round with red plastic covers: Kitchen & Dining : Walmart.com

I get them at the supermarket....or as mentioned.......... Kmart , Walmart, Target, etc.
I use one qt glass bowls.
I don't think all of mine are Pyrex ? ......but they are ...good enough .
