It isn’t easy for me to get to a tool library so I don’t use one, and I understand any hygiene concerns about shared toys (especially now).
But if you need something you’re not likely to use regularly or your kids like variety these are a cost effective option.
Some tool libraries have a low annual membership fee and some have criteria (such as being over 18 and signing a safety waiver). I’m not sure what a toy library involves.
The concept of a tool library immediately interests me because I have so many tools I barely use or have neglected buying because I would only use one to five times.
It’d be much more convenient to grab exactly what I need for a project.
