I have seen many mermaids who have tails with one color so I figured they would like this. Some don't care to have designs and such. Also the reinforcement would be like what other tail makers already do for the higher price they charge. I don't think other makers do near as much extra silicone in sensitive areas like what mernation does because in unboxing videos and pictures I can tell mernation added a lot and make it very tough and it doesn't look like that at all in other tail makers video unboxings and pictures and I already can tell that other makers have thinner silicone throughout the whole tail itself and thinner extra fins. That's why I went for mernation because in videos and pictures I could tell the overall tail and extra fins are thicker than other makers tails and their price is more reasonable than other makers. I want thicker silicone because one it gives support and less likely to rip and second it hides your leg shape better and third kids can't feel your legs or feet as much.
