Terracotta tiles (Brixton Hill SW2)

Unglazed terracotta tiles, size 20 x 20 x 1cm, there are 11 whole tiles but some of these have small chips and 2 have tile adhesive on the back + assorted offcuts. These need to be sealed if used as floor tiles - they were in a box with assorted tile sealant, adhesive and grout which I estimate to be around 20 years old so maybe no longer useable but you'd be welcome to have this too. Collect from SW2 2BT.
