Anti-perspirant roll-on bottlesWe flipped to roll-on ones from aerosol anti-perspirants for environment reasons - both big, out-there environment (the aerosol bit) and little, in-here environment (the spray quickly made the bathroom unpleasant as it deodorised your lungs) - but now we’re left with lots of roll-on bottles instead.

I suspect the bottle and the ball are different types of plastic so am wary to throw them in the recycling bin - anyone know if they can be recycled? Does it help if you pop the ball out first?

But better than that, are there any reuses for them? Either complete or in parts.

And what about stick deodorant containers (the narrower, ball-less ones)?
