What educational hammering toys do parents recommend?

I'm looking for some good hammering toys for my two young sons. I'd like something that can keep them engaged while also helping them practise basic hand-eye coordination and fine motor skills.

For parents who have bought these types of toys, what features or brands would you recommend? I'm especially interested in options that are sturdy, safe for toddlers, and easy to clean.

I'm also considering buying from Alibaba because I'm looking at several toys at once. Has anyone here had experience sourcing children's educational toys from there? What should I check before placing an order?
