No not a stammer, I bought this wee beauty from someone I knew; he makes these and many other things too. Huge amount of skill. The top unscrews and it would be suited to keeping something or things in relatively small.
Anyway I had forgotten that I bought it to use at Swindon 2013 show as part of my accent. I changed my mind at the last moment feeling the ‘hedgehogs’ were more in keeping.
At 6cm tall and 5cm wide and the widest point it is a favourite to use in the future. Thanks to Mark for reminding me it is Boxwood.
