Online it says KSC 0.30g, but the actual bags are KWA. I know they're the same company, but that did bother me a bit. I've noticed a difference in quality between KWA 0.25gs and KSC 0.25gs. The 0.30g are good. I wouldn't say they are the best, but good enough for my custom aeg and KWA LM4s. Quality seems pretty good, I did notice fear imperfections here and there, but that's to be expected. I
Price is good, if you get a deal with shipping, other wise buying these and paying for regular shipping equals the normal costs of 3 bags.
-Good price (when combined with a shipping coupon)
-Good for 0.30g bbs. Nice when they're in stock, because most local stores around me stop at 0.28g
-Website says KSC, but bags are KWA (same company, but not always same QC)
-3 Bag special only saves when combined with shipping coupon
-Not the best, but still pretty good.
