I bought this set about 6 months ago and find that the vacuum seal only lasts about a week. These are not suitable for longer term storage.

We have a large spice collection which are sourced from various companies. These jars are large enough to hold the spice mixes from speciality companies and the ones I pick up in bulk. Additionally, I like the shaker lids with the dual opening options and that I can extend their shelf life with the vacuum. I’ve added the labels so I can easily identify them and how many will fit in the spice drawer. I have had no issues with them.

No Chalk labels are supplied with the purchase of the cubes and you cannot buy them separatly.

These are small as described and probably only practical for storing spices. Overall, they are the same quality as the rest of the product line and have similar accessory utility to them. Unless you have a difficult time storing your spices or you purchase the flat packs of spices, I would start out with 1 or 2 sets and give them a try to see if they are worth the investment to convert all your spices over to these units. You will have to label them and Zwilling does have an app with their system labels that will record what you have in your stock. I bought one set and will test them over time to see if I want to purchase more.

Reallllly poor sealing capability. No matter the spice or herb, within an hour the seal is entirely gone. Without the seal the lid will not stay on and so if you try to lift the item from the lid it will just fall off so you can't even use it without vac sealing. really shoddy product and consistent drop in quality from Zwilling
