AMOS Riichi Mahjong Tray Lids

If you own an AMOS Max or Masters set, you know the struggle: you carry the case for five minutes and open it up only to find the tiles have shifted, flipped, or spilled out of their trays. I designed these inserts to solve the biggest flaw with the default AMOS case where the tiles inevitably shift the second you pick up the handle.
 

These lids are a low-profile press-fit that sits flush against the tiles, keeping everything locked into its row even if the case is held vertically or bumped in transit. They cover the entire tray, including the dice and indicator sections, without adding enough bulk to interfere with the case latching shut. It’s a simple "set it and forget it" fix so you don't have to re-sort your tiles every time you get to a game.
