Question: Is the see-through insert in the lid glass or plastic?
Document: It has a highly polished and therefore slippery, rounded top. If you attempt to stack them, they will slide off at the slightest movement, and that would be a disaster with all the powders inside.The clear lid is not glass. It's a good quality plastic material. However, it is prone to scratches and already had minor cosmetic scratches on arrival.The highly polished stainless steel exterior is also prone to scratches, and had minor cosmetic scratches on arrival.Packaging (of the product, not Amazon's packing):It was very well packed in a sturdy box with bubble wrap and plastic wrap of each individual piece.Looks well built and like a quality product.
I was looking for a masala box big enough that I don't have to refill very often. its big and heavy and clear lid makes it beautiful when you see colors. the lid is loose so you have to careful while handling. otherwise I like this product.
box is very nice but the glass on the lid is not very securely attached - mine came off, warped with less than 1 month of use (I bought two others which are finebiggest problem is not being able to return - i just want another lid
Its not like the masala boxes in india where they are flat. This holds A LOT. Each box inside has its own spoon I couldnt ask for more. I was literally jumping for joy. Now about its quality while i was wiping it down i felt that the steel wasnt cheap the edges werent sharp or anything. The see through lid is not only practical but super super cute with all the colorful spices showing. LOVE LOVE LOVE. I will definitely consider this as a gift and repurchase for someone that cooks Indian.
The bowls on this are very deep. I like the little spoons and I wraped a tiny bit of tape around the end of each to lable my spices. The lid fits on securely and this looks lovely sitting on my microwave. It also allows me to stay aware of my indian spices and use them more frequently than when I left them in the cupboard.My only criticism is, it would be nice if the individual bowls could seal. However, as long as I don't turn it upside down everything is secure and the glass top keeps things surprisingly fresh.
I like the fact that the cover is clear so you can see your spices. It displays nicely and has everything you need all in one convienient location.
A must have item in every kitchen. I really love this masala box and it has very good quality. Worth buying it as you can see all the masala's at the same time and use it. wonderful product.
This container is very good and looks pleasing but the problem is the glass cap that fits in the container top came off on mine and won't fit again. That left my box with out top and useless. Other than that it is solidly built and does the job.
The tin is deeper than any other I have ever had (because has to be able to hold all the individual spoons) -- and I like that because I don't have to refill my spices as often (we cook Indian food for our family 2-4 times weekly). Only con is water got under the glass rim stuck between metal and glass and had to blowdry it out after cleaning for the first time (or the moisture will ruin your masalas). But I don't clean my tin *that* often so it's a minor nuisance.
On my fourth masala tin in the last 20 years (not because anything was wrong with the rest, just kept giving it away to friends who wanted one)... and this is my favorite out of all of them. Clear glass on top to showcase your beautiful array of colored spices. I have never had a separate spoon for each spice! It's extravagant and cool! I mostly still use one because when my oil heats up quickly, I have to move fast to get all the spices in there to bloom them in time, but I love the idea of separates and for slower-paced cooking it works out fine.
Answer: We gave it as a gift and they seem to really like it so I asked...  Reply was; "It seems to be glass. Beware: The top is heavy and falls off easily. So, if you are getting one you may want to look for a complete stainless steel top."  They said as long as you are aware of this it is fine.  Hope this helps.
