Thank you for viewing this item. This is a compatible replacement for the ER-SC2 shoe cover (hot shoe/multi-accessory shoe) that comes with Canon's R series cameras. It is manufactured by JJC. I imported these from China for my own use, but I ended up buying too many, so I'm selling some. If you purchase two or more, you can add additional units for ¥300 each. Please comment before purchasing, and I will adjust the price. Consider having multiple replacements in case you lose one. Although the R3, R5mk2, etc. are officially unsupported, they can still be used, though dust and water resistance will be reduced. Please feel free to comment if you have any questions or would like additional photos. Compatible models: EOS R5 R6 R7 R8 R10 R50, etc. #camera #shoecover #accessory #compatible #multiaccessoryshoe #hotshoe #Canon #CANON
