Tokay Traders is a trading post found in past-age Labrynna in Oracle of Ages. The shop is located on Crescent Island to the northeast, on a small islet connected to the mainland by a bridge. The proprietor of the trading post is a Tokay. The only two items the shop sells are, in fact, Link's Power Bracelet and Roc's Feather, which were stolen from him by the Tokay when he washed up on the shores of the island.
Unlike conventional shops, items at Tokay Traders are bought with Mystical Seeds instead of Rupees. If Link does not have Mystical Seeds at the time, he can trade his Shovel for either the Power Bracelet or the Roc's Feather. When needed, Link can return the item, take back his shovel, and trade it for the other item as many times as is necessary. Doing so allows him to explore the island and collect his items.
Once Link has bought back both items, his inventory will once again be complete. Afterwards, the only item on sale at the shop will be a Shield.
