This set come with three designs, two of each, and retails for £6.50. You get these three designs in the set:
Wooden top with fungus.
Once removed they do look good on model, and as expected, they fit well with other Spellcrow components.
All-in-all, they are a nice addition to Plague Legion/Marine armies, that require a little more care when it comes to de-spruing mould-line removal.
