iDRY - Waterproof phone case (Northern Moor M23)

Currently in the freegle box is (another) thing I shouldn't have wasted my money on in my 20s.

The iDRY is brilliant at keeping phones (or other valuables) dry, whilst still being able to use the touchscreen. Trouble is, I got it for my iphone 4S. Smartphones have mostly grown in size since then, so it's unlikely to fit devices from the last 5-10 years.

Still, could be useful for an older phone or if you have other ideas.
I'll be holding off until late next week to offer this, to make sure it goes to a good home.
Cheers, Simon
