Is this a furnishing? If yes, what is its name?

This would look AWESOME on my alchemy lab.

It looks like Cabinet, Poisonmaker's.
You can sometimes buy it or plans for it at guild traders, or buy the plans for it with writ vouchers from either Rolis or Faustina (I forget which one has it now), where you turn your master writs in.
Also, they are doing bundles now, so it maybe included in Crafters Furnishing Folio rather than sold individually if you buy it with writ vouchers.

It’s the Poison Maker’s cabinet. It’s craftable by players. The furnishing plan or one already made might be available in guild stores.
