This coaster by David Shrigley is giving off a resolutely not opening any day soon kind of vibe with each day's forecast for opening being a firm no way. A coaster for someone who is happy to not welcome visitors when it's time for tea, gift it with the matching Opening Hours mug for a definitive you-can't-come-in approach everyday. 

The coaster is made from cork and measures 10 cm x 10 cm.
