Maybe very cheap, or maybe an error (in which case you will normally get a full refund)

Don't recognise the seller's name, and at < 98 %, < 1000 trades, they're struggling.
Either they're complete con-artists
OR
They fucked up earlier and are now trying their best to get some Positive feedback really fast.
Personally i'd risk just £3 if i wanted to <i>maybe</i> get a 3-neck 500ml RBF.

even though money is tight at the moment, I could not resist ordering a couple
- worst case is phony tracking reference, no delivery, refund.
I was actually looking for a 24/29 or 24/40 socket to hack together something,
I could cut the necks off for £1 each,
but I know that I will not as 500ml/NS24 is now my 'standard',
I'll just wait until I break something
EDIT: Stage one complete, marked as shipped and phony tracking reference received ....

I am very pleased to announce the arrival of two 500ml 3-neck flasks.
On careful inspection each has a couple of tiny air bubbles (that I think are insignificant)
but are made so smooth, far better looking quality than the cheap distillation kit that I bought, thicker, shinier, prettier
I feel a little guilty now - but happy.

Mine arrived today too. Packed very well so they were intact.
No obvious faults and the ground joints are finely ground and fit perfectly with my good stoppers but not with my clips. They were a good price. I am
sorry I did not buy more than two while the price was so good.
I desperately need to get my fume cupboard built but I need to make space for it in my workshop. I should extend the building or for a quick fix add a
shed.
