You could take a hacksaw to an empty tall boy and try and make something like this, but you’ll be left with something far flimsier and jagged enough to make your lips look like the Joker. A better and safer option is The Tall Boy Pint Cup. The 16 oz cup is made from 18/8 medical grade stainless steel and is dishwasher safe. The BPA-free cup looks like it was repurposed from a fun night. For the office, the campsite, or just around your house, it’s a slick-looking drinking vessel whether you fill it with a light lager or just some water.
