Most toys are safe, but there are some brands that may not be as good as others. I like to buy Oxbow toys because they are a pretty reputable brand, and I also make some out of toilet paper rolls and cardboard. Things that are definitely safe are “apple wood sticks” and toys made out of willow.

I don’t have personal experience with all these woods, but https://bunnylady.com/safe-wood-for-rabbits/ here is a list (from what I can see is pretty reliable and presented competently) of rabbit-safe woods. If you cannot find a specific description of a toy on the online website, I would either try to find that toy somewhere else or overlook that toy — it’s always best to know and be able to make an educated choice. That being said, typically toys by well-known, reputable brands, such as Oxbow, are safe. Toys you need to be more vigilant about double-checking materials are those that aren’t actually made for rabbits, but people may advertise them as being popular for “any small pet”.

You can visit the BinkyBunny store and see what materials are found there that make-up the toys. Anything on Binkybunny is 100% safe and OK for rabbits, so if you find a material that overlaps, it’ll be safe as long as there isn’t some sort of change in material processing (i.e. chemical polishing/drying, toxic glues/adhesives…)

I tend to buy most toys online, so I end up just reading the reviews to make sure no one had any problems with it. And when i’m buying stuff in person I end up googling on my phone…. haha.

Some toys are OK to give if supervised but prob best not to give unsupervised. For example there are these wire balls that you can use to stuff hay or veggies in, but I read a review of a small bun kind of getting his head stuck in it, so that is one to just give when supervised.
