I have one of these on the bookshelf beside my piano. And I've actually needed to use it a few times (for band-aids) over the past few years. I got several of these little first aid kits FREE from our local Superstore pharmacy when we lived in Nova Scotia. I'm not sure if they still give them out free, but it's worth asking about! At the time I got several; I put one in the car and one in my piano bench. This particular kit, though small, even includes the supplies for CPR, which hopefully would never be needed. Safety first, right?....even in our studios!
Does your studio have a first aid kit?
