At the dollar store they have plastic bowls all sizes that are semi hard to cut with a blade but if you have a soldering iron you should b good. All under $2 bucks, you kant beat dat wit a stick dawg. Not an item u find at ur house thou.
Clear hides won't make a bp feel very secure. Every snake is a little different, I tried to upgrade my hide sizes for my largest girl and she prefers to wear her smaller hide like a hat or squeeze in under the newspaper in her tub. I'd say give a larger one a try but keep the smaller one on hand for awhile. Remember a snug hide is what they prefer
I like cat litter pans from walmart, I believe the brand name is van ness. 4 different sizes to pick from and they work great from hatchlings to my adult bredli's
