Seal Supplies ltd 2k Scuba Diving ballast

I needed this to weigh down a glu-gun holder that was made with a 3D printer. The opening on holder is 5mm. This tiny balls were 3 mm in size and with a small funnel it fitted easy. I’ve measured about 20ml (medicine cup) and weigh it in at 161grams. Considering I could only fit in about 50 ml in holder, it weighed it down sufficiently without it being super heavy. And I still have a lot left for other projects! Only negative comments I could make, although it was packed securely, opened packed without spilling some balls is impossible. So open it in a container. All I know is I’m going to find little balls in nooks and crannies for years to come...

Good product and fast delivery, but when I weighed it it was just over 1.6 kg including bag. Whilst it wasn't actually an issue as I only needed 1.2 kg i do feel slightly annoyed in principal as I ordered 2kg.

Product repackaged and resent perfectly
