I sent you a few videos and ideas on IG to improve the design of the case. Very satisfied customer and plan to be back when you release the 4 booster pack case.
I'm really pleased with the quality of the ETB cases. They're thick and not too tight compared to some other cases I've used. The magnetic cover is really sturdy. The PSA slab holders fit perfect and look great as well. Will definitely purchase more!
I ordered the slab holder and the ETB holder and both work excellent.
