Grabs are item sets that we release into the game, and oftentimes we'll release multiple grabs per week. You can win new items by visiting the Shop to peruse the catalogs.
The main way to spin items is through the Shop. Tap on the Shop icon in your bottom menu, and from there you can view 'Featured Grabs'.
If we have a live event going on (these change around once a week) then you can also check out the new grab in the Event Room. Tap on the event icon in the lower right of your home room screen, and from there navigate to the top of the event menu. Check out "Go to Event Room" to spin some new drip!
