They are anywhere from $250 USD - $350 USD and include a custom monofin, bikini top and bottom and tailskin! They are made in Germany but we bought the tails and had no issue at all with the site or the ordering process, it's reliable. You need to be a good swimmer and be really careful not to damage your tail. Letting in scrape the bottom or sides with your tail, hitting the bottom or sides with your tail, sitting on any surface that could damage the fabric or trying to stand up and/or walk in your tail WILL wreck it! You can buy replacement monofins, tailskins or bikinis if they get wrecked or become too small to fit.
