I have found a couple of websites that offer some great Celtic FC items.
The first one is Nostalgia Cases where you will be able to find both current
and vintage Football Shirt Phone Cases.
Just click on the link below and then select Celtic in their search box.
The other website I have found is Soccerbox. This is a great place to
find Football Shirts, Soccer Jerseys and Football Kits, not only for Celtic FC
but for many other clubs both UK and worldwide. Just follow the link below:
