pete,i send you 4pcs of ball transfer sample,they are from two supplier.
i stick paper label on sample,1# is from shanghai supplier,2# is from shandong supplier.
in my opinion,i think 1# quality is better than 2# quality.
1# factory said the size is same as our drawing.and 2# factory said size is a little bit different with our drawing,and if we order,they can make according to our drawing.
