Can you look at this purchase listing for beads & tell me what it means?

Please see the image. It's this bit I don't understand: '0,15mass in 1 bag'
I understand you're purchasing in bulk at 250g. One bead weighs 2g. So what does that last bit mean? There are not 15 pieces in one bag.

are they using mass to mean weight? But that doesn't make sense as 0.15 would be 150 gram, but they also are saying 250 gram bags? sorry very confusing description!

I buy beads a lot and am curious to know!

It's wholesale, so the minimum purchase is a 250g bag. 1 unit = 250g

Where do you buy beads @disneylover367 ?

I buy them on Etsy and eBay, but they tend to be expensive here as they are sold by re-sellers. But if they are vintage I know I most likely wont see them anywhere else so I will buy. I have bought larger quantities from Alibaba and Indiamart and found them really good quality and price, most sellers will sell smaller quantities as well. Postage can be about £15.00 as some beads are quite heavy as you probably know, especially glass.
