This is an 8cm vinyl sticker featuring my illustration of Bigwig, and the Lapine words "Silflay Hraka".
Lapine is the fictional language that the rabbits speak in Watership Down. Silflay means to feed, and hraka means droppings, so "Silflay Hraka" translates to "eat shit". At the climax of the story Bigwig uses this phrase to effectively swear at General Woundwort during their big fight!
The stickers are weather resistant, printed on heavy duty vinyl with a strong adhesive backing.
