If this is open to more information, I’ll start by saying ordering from any Chinese supplier right now is going to be a challenge as the holiday begins. However, I have one for 4cell angled style and 2cell squared style 21700 and 18650 holders that would be cheaper than this. The angled ones have a flat top and the squared ones have plastic bits over the top like these that would make wide nickel strips harder to use.
Holiday or not, I prefer to get this in EU and not China.
“cheaper” is also not the point for me when I pay 0,01 Euro more per cell for some holders I can get in 2 days.
