Very smart cylindrical glass jars with fingerprint resistant bonded plastic outer and screw top plastic lid. This set of three (black) canisters each has a one litre capacity and measures 10cm (4") diameter and 17.5cm (6.75") tall. An elliptical cut out panel in the plastic outer allows contents to be easily seen.Each canister weighs 720g when empty and feels nicely balanced and solid in the hand. The screw top lid is well made.Each canister comfortably holds 40 - 60 teabags (will take 80 at a push).Will hold up to 250g coffee granules.Will hold up to 750g granulated sugar.A canister will also comfortably hold up to ten of the taller Kenco or similar brand Latte or Cappucino sachets, or the tall single sized sachets of hot chocolate drink.My other half has just said, "You didn't actually count and measure how many teabags and stuff you can put in one of them, did you?" Well, actually I did, for the purposes of this review.He is still looking at me with utter bewilderment. I guess I'll just have to take one for the team, in bringing you what I hope is useful review.All in all, this set of three canisters makes a smart addition to kitchen decor - they'll team up well with similar coloured small electric appliances on the worktop.Roomy enough to hold plenty of tea/coffee making essentials without the descriptive"Tea" "Coffee" "Sugar." signage, which I've always found a bit restrictive, as well as irritating, (but not as irritating as my significant Other), and will clean up well with just a wipe from a damp cloth.I don't think they'd appreciate being put through a dishwasher - I think the plastic bonded outer would suffer. Just like someone else I know who will, very shortly.Hi, we needed four containers so had to buy six. We failed to get four satisfactory items from the six supplied so we arranged to send three back. We ordered thee more. However from the nine jars and lids we were only able to obtain 5 that we were entirely happy with. We have sent three back and retained six.I have included the photos of the finished installation of the four so you can see they look good. I have also provided images of the worst of the imperfections. You may think I am picky but I think they should be right. If they were from a pound store then they would be fine for the price.I bought these storage jars because i love that they are just one colour in black, I’ve bought from premier housewares many times and i know every purchase I’ve made have been a great purchase, so when these arrived i was not disappointed. I would recommend these storage jars.Worth every penny. They are heavy and sturdy. The jar itself is made of solid glass. The screw lid is metal and the whole jar has a covering the same. I'm finding that fingerprints are not an issue unlike my previous set of canisters. Easy to clean with soapy water. I much prefer the window type of canister as my previous set had the lettering wear off.These are not that easy to clean as when you get them wet it seems like the layer in between the glass and metal gets steamy? So you need to let them dry out for at least a day before you put anything inside (in my opinion). Other than that they look great and keep items inside like tea, coffee, and sugar nicely fresh
