Hello folks, what kind of small bubbler do you recommend for the vapcap ? I know and own a D020 bubbler. It's great and has a good size but it's not so good for traveling. sneaky pete has some nice smallish glass items but they are very very pricey to get to the EU. I've been lurking on DHgate for days now but did not find a small bubbler for the vapcap. What do you use for water-vapcaping on the go ?
