Camera probably won't be able to show the difference, so a detailed description would be better. Maybe expose the scrap to room light for 15 minutes, then turn off all lights and time how long it glows? The current material glows great under blacklights and when just entering a dark room... but is not noticeable at all after a few seconds, 30 maybe, in a semi lit environment.
No point in wasting more money on it if the gtid is not much better.
As far as the quality goes, let stick to the higher quality ones.... but please we will need exact measurements or to know that they are the same as in the last order.
I really don't want a repeat of the 4x mini tent polo fiasco
Definitely looking forward to a few more of these
