Must Have Ideas
I ordered a perfect peeler and a tin tastic and both of them are amazing. The tin tastic would be perfect for someone with difficulty opening tins with a normal tin opener. This isn’t the first time I’ve ordered off these guys and I’ve never been disappointed. Really quick delivery also. Would highly recommend this UK based company
