Use these simple steps to professionally add a buttercream rose. You'll need a spatula, rose tips, a leaf tip, couplers, a flower nail, a rubber spatula, and piping bags.

    In providing easy interchangeability for decorating tips, these couplers save a decent amount of time and equipment usage and free up workspace as well. They pair perfectly with Ateco's Plastic Coated Pastry Bags - a small investment with a huge payoff!
    The only coupler we use and order are these ones! Ateco has quickly become our favorite brand to use. The merchandise is made very well and lasts a long time. We go through couplers often so this is a great deal and lasts us a while!
    i just star using this Ateco 400 2-Piece Standard Plastic Coupler and i love it !! it lets you switch pipes without changing plastic bags !! great item
    This performs as you would expect. If you're looking for something fancy, this isn't it, but it will do what you want without complaining or asking silly questions.
    These are great! Very sturdy and seem like they will not crack if i tighten it alittle tight like some have done on me which is annoying
    The Ateco 400 2 pc standard plastic coupler is a must have when piping! It is a huge time saver because all you have to do is switch out the piping tip. No need to grab another piping bag.
    local stores will charge as much more for this item while here it was 1/10 of that cost, works exactly as designed, well worth it
    I really like these 2 piece plastic couplers. They work well and were a good deal for the price. I use them with the disposable pastry bags also from webstaurant. Great combination!
    this 2-Piece Standard Plastic Coupler works great and is a must have product! we are happy with this product and will be ordering more in the future.
    These couplers are great! I like that they don't have the notch out like others, so you can use it as a tip for a big circle and not have to use another bag with the big tip!
    I will order these over and over again! Love these more than any additional ones I have purchased previously! Fit together perfectly with no issues
    The coupler is a must for piping. One piece on the inside of the bag, and the other works with the tip, screws together easily. It comes in small, medium and large to fit different tips. Excellent.
    These Ateco standard couplers are a classic. Work great with disposable or washable pastry bags. Easy to change your tip type on the fly! rather then have separate bags.
    So perfect for when you are layering a cake. It gives you an even circle for you to put your filling in and layer everything evenly. I love this tool and it's also very easy to change your tips. So you use less pastry bags !
    A bit smaller than I was expecting but its useful if you are working on small detail piping and need to swap back and forth between tips on the same piping mixture.
    This Atecco coupler is needed if you change tips often. They are very easy to use so changing the tips is simple. The atecco small tips fit perfectly. Very good price. I will buy more
    This works perfectly, there are no leaks and the connection is very strong. This product is excellent for the price point, I would highly recommend to anyone.
    Super easy to use and to store! GREAT price, non of the items cam damage which is a huge plus. I use this for all my decorating needs. Will recommend and purchase again!
    If you plan on using multiple tips a coupler is a MUST and these are cheap and good quality. Been using mine for a while now and have not had any issues. I recommend this to anyone who likes to play with piping tips.
    This 2 piece coupler is very easy to use with disposable or reusable pastry bag. It is very easy to assemble and works with lots of piping tip
