Does your borosilicate cup feel and sound like plastic? Also does the exterior of your cup get hot? I'm wondering if I was sent the wrong product.

No, neither of both. Mine were perfect glass (we dropped one on a ceramic floor and it exploded like a light bulb, with real glass splinters), cold outside with hot tea, quite strong except for that episode. I am sorry if you did not get that.

Mine feels and looks like glass or a VERY high quality plastic. I've never felt it get cold or hot on the outside even when my espresso is steaming but the inner walls do kinda fog. If its REALLY hot then the outside might feel slightly warm but its barely noticeable. Maybe you have a defective one? Im not sure. :(

This cup feels like glass. When i flick the side with my nail, it sounds like glass. When I pulled an espresso shot, there is a slight warmth to the outside of the cup (the shot is very hot).

Hello no it doesn't feel or sound like plastic The exterior of the cup doesn't get hot

It does not feel at all like plastic, but very thin glass, and it does not feel hot with espresso or hot tea.

Mine didn't feel plastic, but when I tried drinking coffee or tea from it, it just felt wrong. The edge was too wide.... Not an interesting experience

They don't taste metallic, but they feel super weird when you drink cold drinks through them. They are definitely a different experience than your normal plastic straws. I personally don't like them.

This gets hot enough to touch but doesnt heat my mug well. I would not put a plastic tumbler on it, it will melt it for sure.

I have used the cup for heating milk. I did not feel any noticeably heated surface.... just a bit warm because of heated milk inside.

You need to put boric acid or diatomaceous earth in the cups. Both are available in Amazon. They have worked fine for me.

I'm sure you used the term glass for,cup, but let me first point out that it is plastic-- not glass. In answer to your question, there are no rough edges on the outside of the top of the cup where the top screws on. It is flat and feels nice against your mouth when you drink.

It looks like steel (its definitely some kind of metal). I tell you this cup is awesome. And I am someone who uses two cups per day (I go home to make two cups of coffees per day). So lot of use. BTW I have always washed it in dishwasher on the top rack.

The cup gets hot, not as much as a ceramic cup, though. And the handle doesn't get hot at all.

I haven't dropped my mug, yet....my husband says he thinks it is stainless covered with some type of epoxy, something that is insulating. I tried scratching it....it will scratch...I used a bottle opener....but it does not look as if it will chip...hope this was helpful....I recommend this thermos cup.

I am pretty sure that the cup is made of a silicone based material, and I have never known it to smell funny. That being said, I have never used it for coffee or other hot, strong smelling liquids. It has never added taste to a cold liquid, but I am not sure about hot liquids. It says it can withstand temperatures of 180 degrees, so you should be fine with coffee, but I have no definite answer.Hope I could help, and sorry I couldn't give you a clear answer!

Dear Kat,Mine has no distinct odor from hot beverages, Smell depends on the amount of sensors in any individuals sinuses.The cup is a silicone bas material if that helps any. Thank you and God bless.Joseph

If memory serves correctly (I gave it as a gift), the top was shiny stainless on top, regular on the underside. Remember that this is a French Press; thus, there is a hole straight through the center of the lid for the plunger. Accordingly, the lid does not offer any thermos-like thermal protection. NO product will keep your coffee piping hot for hours on end. Unless, of course, you care to spring for a double- and triple-wall borosilicate glass vacuum bottle inside a live-steam-circulating pressure vessel. Sorry for seeming to be rude here, but you're looking for something that does not exist outside of a research laboratory.

Mine didn't come with insulation. I didn't have a melting problem, but I am not sure about at the height of summer, particularly shipping to HI. FYI, I prefer now to order from another vendor in GB, as the larger volume didn't taste quite right. A bit dried out, or stale. Kind of woody. The lot I got had Arabic writing on, so I am not sure if they were a particular recipe for shipping to that area. The Flakes from GB are sold in lots of 6, and are occasionally the smaller size, but taste just right.

Actually, they feel more like ceramic. I also have cups that _are_ made from the same material as the plates - they're shorter, wider, with smaller handles. These are not the same. These do feel better in the hand, though.

This was hard to tell because the black plastic covers the bottom outside so you can't tell visually. But I drained it and felt around inside (there are some odd ridges and bumps) and it all felt like glass. Hope this helps.

Rebecca -- yes it is and it is great tasting. Tip I learned -- if you like it lighter, adjust cup size to larger, if you like it stronger, adjust to smaller cup. You get the great taste with just the right 'robustness'. Enjoy!

Under the leather is real felt. The cup feels like real leather but it may be synthetic. In any event, it's very nice.
