I love the light blue knobs on intellijel modules. Any idea where to get them (and what size) in North America?
To my knowledge, I don’t think anyone in NA has them. Your best bet is Thonk in the UK:
What exper said. I’ve ordered a TON of those (and other stuff) from Thonk and with the cheapest shipping (@ $10) it usually takes 10-14 days (sometimes less) to go from the UK to San Francisco.
