My condolences to them for their loss.
Mart, can you please get them to post pictures of the the open wooden canister as well with finished inside measurements. ALSO, can they smell the cannisters - any scent?
Reminds me of older cabinets that were used in shops for teas, spices, medicinal compounds, incense and the slanted shelves would hold various pieces for the purchaser to hold said purchases.
However, it also brings to mind older cabinets that were used to hold writing implements and the slanted shelves would hold stationary.
