My thread is not the cone thread. I use Connecting Threads thread (love it) I purchased their thread cases, see through and holds 48 spools, opens from either side, and has a handle for carrying. I think they were around $10.00 I bought 3 and really need another. These are very nice, don't take up much room, (stack them) and keep my thread nice and clean. Catch them on sale and you can get them even cheaper.
