I have had great success the last few years swapping unwanted/unneeded/mistaken gifts. So I shall start.
Oral B Pro-Expert toothbrush with batteries (not one that sits on a rechargeable stand)
Colgate Proclinical 150 battery sonic toothbrush.
Both brand new in box never opened or used (asked for rechargeable one and got 2 battery powered ones!)
Swap for mint chocolates, smelly candles, craft lager or open to any other suggestions!
