Arcam music boost iPhone case

iPhone 6 / 6s Arcam music boost case.
No longer needed as my new phone doesn’t fit.
This is a battery booster , DAC and headphone amp. I wouldn’t recommend using it solely as a case as it does leave quite a bit of the phone exposed. I used it mostly for the dac which was a significant improvement over the phone imo.
It was £120 when new but they’ve dropped considerably in price now.
How does £25 plus postage sound ?

Note , phone isn’t included. Just shown to show how exposed it is.
