They're made of metal!
Only if it fractures or a piece chips off, which is highly unlikely given that it is made of solid metal. Perhaps if you smashed your head into concrete, a few atoms would be abraded away. It's best to set it down on a soft surface.
They're accurate, and I used a different weight (U.S.) to make them. Coins) were used to verify their accuracy, and the weights were found to be spot on.
No, there aren't any storage boxes; they're tiny and came in a plastic baggie.

I needed these calibration weights for my small business, and they were perfect! I ship about a dozen packages per week, so accuracy of my scales was critical. I previously used a scale that was too low. As a result of underpaying for postage and delaying the shipping process due to weighed packages, I now add a few ounces to every package just in case. But, as shipping costs continue to rise, I decided to invest in these calibration weights so that I can have peace of mind knowing that the number the scale gives me is accurate, which will save me a lot of money on shipping costs over time! It also helped me see that my main scale has a hard time reading weights of 5 grams and under, which I need it to be able to do at times – so maybe it's time for a new scale! Fortunately, I'll have these fantastic calibration weights on hand to put the new scale to the test! I would strongly advise anyone who needs to check the accuracy of their scale to get one of these!.
These are low-cost and appear to be so. It's more important that they're reasonably accurate. On a scale of 1 to 100, this is the result. Scale with 1g precision: 100 1g, 50. 1g, 20. 0g, 10. 0g, 5. 0g, 2. 0g, 1. 0g.
These were purchased to calibrate my postal scale, and they are well-machined, precise weights (when compared to a partial set I already had). I'd like identification stamping that is more visible - However, I'll most likely just paint the marks to make them stand out more. Overall, a good set for the money.
Not only did this set of weights give me the 100g, but it also gave me six others. What a fantastic bargain!.
I needed something to check and calibrate my small scale, and this was exactly what I needed. Delivery was very quick. Everything went according to plan.
Please consider adding an additional 2g and 20g to cover the range of 1 to 200. To make it work, I'll need to purchase two sets.
This was used to calibrate the precision scale I was using. They appear to be of good quality and arrived on time.
These weights were purchased to verify the accuracy of my scale and, if necessary, to calibrate it. When I weigh the weights on my scale, they are correct. It's reassuring to know that my scale and weights are both precise. I am a happy customer who would suggest this product to others.
