I use Alpaka Zip Pouch Pro as my wallet, so the SwissCard is in my wallet, Pioneer and Open Mini is on the pockets of the wallet, Tini2 is on my car key, Squirt PS4 on my home keys (that are kept in a Orbitkey organizer), the Tread on my right Hand, because I have the watch on left hand and the PST in the pocket with the wallet.
I don't really feel them, but it's the first time I take them all in one hand and I thinking is a little bit too much.
