They are the same. IN United States they are sold under “old glory” or “command decision” 15 mm
Skytrex has them as well.
It really comes down to size of order. Skytrex will sell you them with free shipping as long as your order is about $300+
(you may have to ask for the free shipping by email before placing order–-say you want to place an order for $300 bucks and can you get free shipping) The free shipping is not found on the site.
The price per bag of 50 Infantry is about $14-15 range, plus you need the washers to support the base, and a bottle of glue.
