I originally found out about the SiliPint back in 2010 when I completed the Bend Ale Trail in Bend, OR. By visiting all of the breweries in the area and collecting each of their stamps on your visitor passport, the visitor center would gift you a Bend Ale Trail Silipint. Ever since then, it has been one of my favorite cups. Recently I wanted to order a few more and was delighted to see all of the new offerings and styles. I saw that they are now offered in Glow in the Dark and I had to have some. They glow really well after exposure to regular lights in my home and day light, but if you want a super charge experience blast them with a black light for a few seconds and enjoy the glow! Also makes for an incredible psychedelic shower beer with no fear of broken glass in the shower. I would highly recommend this to anyone for any situation you could need a cup for. Something that some people don't realize, you can bake with these bad boys in the oven so making amazing desserts right in your favorite is totally a thing!
