While the product shot for these glasses creates the impression they are tapered (wider at the top), they are in fact tall and very skinny. The glasses are 10oz US, which equates to about 290ml, so while they are tall, they're rather skinny and won't hold an entire beer!
They glasses are nice and thick however, and the print is nice quality (the halftone pattern is reasonably tight), so well worth a purchase.
If you can wrest them off of the kids, I recommend filling them with gin or vodka, doing a marathon of the original trilogy, and taking a massive hit every time anyone says “use the force”. Please note that “I have a bad feeling about this” is a mandatory empty-vessel!
