Glass Lily pipes

[Fisher2007]

I've been looking at glass Lily pipes and notice that there seems to be a big difference in price depending on where you buy them from but on the face of things they identical?

The ones I'm looking at are 16/22 and one pair (In and outflow) is £45 from one place and the other pair are £19 however photos look the same

Relatively small changes in shape will significantly affect flow, you'll likely also find that some glass is much thinner, there may also be differences in glass quality (ADA virtually disappears, another brand I've seen in the same display shop was "visible")

I decided against investing as I've not the budget for the ADA set & my two alternates weren't available locally (shipping was substantial)
AND I've been on a glass breaking binge 😳 😳 😳

I'd suggest choosing a midrange price set that is returnable if you're not pleased with it
or look at sets IRL
