Click on Yuni's twip Banner on her Twitch Profile Page

Then login using your twitch account

Then click YuniCoin (유니코인) on Yuni's twip Donation page (red circle)

Click the confirmation links (red rectangle) for Follower and Subscriber (획득 확인) to earn YuniCoins for existing followers and subscribers. Follower coins are one-time only, subscriber coins will be earned upon each renewal.

Just below your user name will be three links. The first page is shown below, How to earn YuniCoins (유니코인 얻기)

The second page is the redemption store (보상 구매하기). The third page is redemption history (나의 보상).

The redemption store should be self-explanatory :) Ask in channel if you need further assistance.
