This plastic bobbin is for rolling up the twine for the trellising of climbing plants like tomatoes and cucumbers , As the plant grows/climbs, it allows for the release of more twine if and when required
Supplied in Packs of 10
I ordered this because I saw it used by some overseas YouTube videos. Its really handy and you can unwind the string from the bobbin as the vines grow and the need to wind it around the plant. I hope to see a lot more useful garden products such as this one.
I haven't used them yet, but they look very strong.
