0.5mm Kalay Kurşun Akı 1.2% 60/40 Reçine Çekirdek Lehim Lehim Kaynak Teli Gümüş

I love this product to use on micro electronics

THERE IS NO INDICATION ON IT HOW MUCH IT WEIGHT! When I ordered it, I remember that the advertised weight was 250g, but I only received 150g of half-filled rubber in the package! Where did the missing 100g of solder go? Why isn't the weight listed, but it's not because I can't check it? There's no invoice anywhere on it, but from the price you can conclude that it's missing at least as much as they lose by selling it at a discount. I can also say that they swallowed the discount they used to stun customers!
