Tanks/Weight

Have here still 2 bottle feet lying around which I no longer need. Suitable for 10L bottles, they should also fit on 12lang if I have that right in my head.
As can be seen in the photos, they have more holes than normal so that the bottles dry faster and do not rust so easily. Feet are used but this does not interfere with the function.
I would have thought 12.50 VB
