I'm reluctantly selling all my Gocco gubbins on ebay at the moment, including these lovely yellow bulbs. I tried selling it as a job lot, but it didn't go, so I'm separating out all the different elements. Please do take a look if you're interested or need to top up your supplies here.* The machine itself is not up yet, but will be in a day or two. Thanks.
*If you're also interested in retro-style dresses, I've got two up for sale there, too!
