I really recommend the case I got https://www.amazon.co.uk/iGadgitz-Travel-Nintendo-Shockproof-Carrying/dp/B071Z2VZP9 Just like the one in this post, it protects the directional sticks while transporting. As mentioned, if travelling with it, I would definitely suggest not buying a case that sits flat against the joycon sticks, the like one @RiverDragon8 suggested unless it's just got light protection at home. No offence RD8.
Looks decent, but the gigantic ‘AMAZON BASICS’ on the front is entirely unnecessary.
I literally bought one last night ffs (lol) (lol) (lol)
This. Did the exact same. Heat for this. The only other real hard case i can find is an uber expensive style also used for sidearms and I think the border controls in the airports may object to seeing that in my case...
A bit of a tip. I have a very similar case to your eBay one and packed headphones in the pouch bit, managed to crack the glass screen protector while in my backpack. I think because of the headphones. Since then I put the screen facing away from the extras pouch.
