I’ve been thinking about this a lot the last couple of days. My current set up is a bag for six from magicyoyo which is sadly sold out in the US. It’s great for about $17 and I like it a lot. It has a generous amount of foam padding for side to side protection and has room for extras. On the downside, the shoulder strap isn’t detachable and I’m thinking of cutting it off and replacing it with a strap with clips that would anchor to the metal rings sown on either side. My biggest issue though is that it’s just too big for traveling. It’s great for picking out stuff that I want to use and carry around at home for the day. But it’s too bulky if I need to carry something else besides yoyos. For a long drive somewhere or if I need to board a flight, I want to pack as light and lean as possible and I’m looking for something really small that I can throw into my backpack that will keep things protected and won’t take much room.
Currently my travel solution is the blue x1 yoyo bag that I use to carry something in my backpack when I want to bring to it work. I think it came with a zeekio yoyo I bought a while ago. It’s basically a step up from a paper bag; it doesn’t offer much protection if it gets dropped or knocked around. But it’s better than nothing.
A case for 2 yoyos I think would be ideal but unfortunately there aren’t many options out there. I was looking very hard at the Sochi case but ultimately I passed on it. At 6.5"W x 5"D x 2.5"H (16cm x12.7cm x 6.35cm) I thought it could have been a bit smaller. For scale the two yoyofriends boxes I have in the picture are together about 6.75" x 3.37" x 2.5". (17.2cm x 8.4cm 6.35cm). I think something that size, smaller in the “d” dimension, would be great. Also the Sochi case is black, which in itself is fine, but my backpack is black and so is my luggage. It’s hard to find black containers packed in black bags, especially in low light. I think if they had the Sochi in bright colors, or really anything other than black, I would have bought it. If someone could post photos of the Sochi with yoyos in the case that would be nice. Unfortunately the Sochi is also sold out, but I’d be interested in seeing what I missed out on.
Per @ChrisFrancz 's suggestion, I think I’ll take a look at camera lens bags as an alternative. Right now if I had to travel, I think I would tape up the two Yoyofriends boxes with bright colored tape and throw them in my backpack.
