To take a quick break from the Purple Heart's, I'm showing the solution I found to carry my new capsules.
A while ago here, I saw the SS gold plated Airvape capsules recommended for the TM2 (they fit similar to the S&B ones, under the stem). They work really well, better than the official ones, and I believe the gold platting makes a difference with the flavour (but I understand that's very subjective and prone to bias).
The only issue with them is that they come in a paper container, so
I ordered a small metallic box as a more permanent solution and it finally arrived. I set up a bit of foam in the bottom so the capsules fit better and do not scratch on the bottom, and a bit more foam on the side also to make them fit better. This is the result:
And this is now my "on the go" set:
It works well, IMO better than the typical tubes as each capsule is accessible individually. In a second iteration I would like to have carved foam with a fixed place for each capsule, but with how small the space is and the tools I have, I did not manage and settled for what you see. Suggestions accepted.
Overall, it's very cheap, small and works great.
