Polished Stainless steel mosaics

[chris.tiling]

Am in desperate need of two sheets of stainless steel polished mosaics. Have fixed half the room and when starting the second half found that the other two sheets of mosaic were a different size. Sheets I need have 12 rows of 12 mosaics each being 22 mm square.
Tile shop have chased the supplier (O&H) who state they dont sell these, only retailing the 11 rows of 11 at 25mm square...but I have used the first two sheets out of the box which were the smaller ones.
Not sure if tile shop has put two batches of stock together, but need a solution, not a person to blame, so has anyone got any ideas?
Thanks in anticipation
Chris

These must of come in a box, is there no information on that.....

The four sheets came in one box and the suppliers (O&H) say they dont make the smaller ones, hence me thinking the retailer has used some old stock and some new. The reference on the box is for the larger ones.
