I have a 4" phillips head up for grabs, if you want it. It’s currently in my back tyre.
Will swap for an empty swear box. Mine has just been filled up.
Grab a puncture repair kit from Infinity Motorcycles for £15, then the swear box is significantly smaller and able to cope a bit better. You can keep it under the seat too. I’ve got one thanks to a couple of incidents with nails!
