i always want to buy the tray for cup to hang inverted and dry easily , now i lost my job i suddenly got an ideal to dry my things with egg tray instead of spending money.
I once saw a ice ball wine video and suddenly ideal spark how to make ice ball , which is done easily with this mochi tray
this is brother ideal I just cut it half
