The width of the pin strip is 0.5cm. I got it from moglo.co.uk and it’s been on for almost a year, in rain and shine and has weathered well. So, I’d say well worth the price. Have also added more stickers from speakstick.com. It’s only been a few weeks but pleased with them too.
You can find the moglo stickers on Amazon and ebay but I’ve found it more economical to buy directly from their website. Of course, there are other sellers/options.
I love my Model 15 and am sure you’ll find yours a great delight. All the best in finding the tape/stickers you want and in giving your bike your own personal ‘touch.’
