Hi Sarah,

We still have the 15mm Aluminium Honeycomb with in the 3.2mm and 6.4mm cell sizes. It is available on the website; we dont; have the 19.1mm cell size in 15mm thickness (but we never have).

Let me know if you have any issues finding it

We have previously had 15mm aliminium honeycomb from you but this is no longer listed - can you supply? 

Regards
S
