CJ Stroud signed the Houston Texans Custom Adult XL Football Jersey in black sharpie. Jersey does have a small black mark at the bottom of the jersey as shown in the photos above, which is why the price is signficantly lower then other Stroud signed jerseys. Signature and COA can be verified on the PAAS Authentication Website along with the hologram number attached to the COA/Jersey. Any questions send me a message anytime.
