I think that the base on this one is insulated to keep the butter cold longer...a neat feature but an even better feature might be to make a butter dish and lid out of sustainable materials.
I had been looking for a good butter dish for over a year when I received one as a gift. When I was looking I was surprised by how lame the options are at retail.
Because you asked, here is another picture of holiday gift idea number two. Designed here at Evo by Mike, Julia, Taesuk and Mohan. I think it makes a great stocking stuffer.
Ok, this may be a bit pricey and difficult to get someone as a gift but the simplicity is cool and it is still less than the watch below. Karl V, I think that this would look great in your place.
