This is just a very simple case for you to be able to slide a TCG Toploader into for extra protection.
I made it for people who use letter envelopes when posting. I myself feel that cardboard is not enough and can be bent.
The inside of the case is about the perfect size for it to not move about. If you are sending a card in it, please do put a piece of tape over the top so it doesn't slide out.
I had the idea for this a while ago, but I only actually modelled it after watching this TikTok (https://vm.tiktok.com/ZNdeGx6cu/) because I realised it was very much needed.
I am not responsible for any damage caused while using this.
The author marked this model as their own original creation.
