While visiting this Polish store, I discovered another brand of plombir by Legendairy which seems to have an address in the UK.
Compared to Eisprom, there are more flavours and the paper wrap is colourful.
I ended up trying a few because of the flavours.
Pistachio and caramel were my favourite.
Mint chocolate wasn't bad but I think I must have got a bad one from the batch because it was dehydrated.
They also had other flavours like banana, bubblegum, chocolate, vanilla and strangely CHEDDAR CHEESE etc.
