Jen bought 2 sets: supplied two blue and two pink to 2.14.
Most:
The plastic is solid.
The closure keeps well and not souvre accidentally.
I use them to AA eneloop pro 2450mAh batteries.
Cons:
If you want to hang two boxes (or more) together, they will not hold.
Laccroche between the two clubs is virtually nonexistent and dislodged themselves.
System well thought but poorly machined. Too bad, it could have been more.
Delivery time a little long.
In short:
As for me, my batteries are stored in boxes that close well.
So happy with my purchase and I recommend this product.
