I’ve not seen these before, but as we wandered around the obligatory shop exit at RHS Wisley I’ll admit to being rather taken with these. Not only for their use of cardboard, but also because of their texture and functionality.
They’re made from recycled cardboard, and are described as a cardboard vase on the packaging. It looks as if they’re French, though so far I’ve failed to find a website for the company, or brand, cache-cache. I’ve found them on websites
They look to be pretty reasonably priced too. The taller necked vase in the background of the photo below is around 28 Euros. When I spotted them at Wisley, I assumed that they’d be readily available and easily findable online, but it seems shopping in person might need to be the approach if you’re interested.
There’s much to be said for the simplicity of this sphere, though I’m sure over time it would become a dust collector. But with such great form and texture, that could be endured, even just for a short while.
