If you love the MAC #225 and are sad about it being discontinued, this is perfect for you!
The Inglot 4SS brush is $22 USD. You can not order online, but you can always call the Inglot store closest to where you live and have it shipped to you! I only know the NYC number, which is: +1 (212) 247-8169.
Otherwise you can always look for the MAC #225 at your local CCO (Cosmetics Company Outlet / Google will tell you where they are) or on ebay.
