Extra Photos of the Yellow dye only. in a 1 pt glass.
8 drops is a bit over kill for any water cooling system about 4 drops will do a 1.5 Ltr to make it nice UV bright but going to 8 drops just give a mental Yellow with a red effect. Quite different to be honest.
So a 10 mil bottle will fill approx 15 to 30 Loops depending on amount used. not bad really. These can be made for as little as 50p to 80p per bottle. The bottle being the most expensive bit. (if buying 1000 bottles then there 5p to 8p each)
Add to the fact that we need to make a profit if we go retail so 50% mark up for maker is £1.60 then 100% mark up for reseller is £3.20 then added vat on top at 15% £3.41 to fill 15 to 30 Loops.
at the moment the dyes you by will do some times less than 1/2 of this at double the value. So this would not only cut the cost of the product but allso increase the amount it can be used.
Personally if were only getting 1/2 the product then we should not be paying so much for it..... again though this is just a personal thing.
Another note to consider as well is that these bottle that they are delivered in destroy 1/4 the die before you even get your hands on them. They should really be delivered in a brown glass bottle as this stop degradation of the fluid before it hits your hands. How ever this is more expensive to produce as the brown bottles are much more expensive.
if how ever these were sold in powder form for as little as 50p per bag this would save on packaging and allso the environment.
