Dear lookandbuyme,
BHFO is the largest clothing seller on eBay. The eBay website is able to
recognize what item specifics eBay sellers are creating and using on
their listings. If the system recognizes that sellers are using some
item specifics more than others, then they it is made available to
sellers through the SYI form. Due to the size of BHFO and volume of
items listed using their item specific, they are directly influencing
the options for item specifics on the SYI form based on how frequently
it is being used on the website. eBay will continue to monitor the
impact of this issue on other sellers but in the meantime, it is up to
the individual seller whether they choose to use this item specific or
not.
It is my pleasure to assist you. Thank you for choosing eBay.
Sincerely,
Ryan Fr.
eBay Customer Support
