This are custom pillow forms or inserts made in the USA.
Because of the way they are filled, you do not need to order up 1 size to fill out your corners.
Cover is very nice, high thread count cotton.
Fill is a soft feather (no large quills) with 5-10% down.
This fill is the company's least expensive feather pillow but it is not a "cheap" pillow. I have used this insert for my custom pillows for many years. They hold up well. Can be washed & dried many times. They will make custom sizes for you. Timing is around 1 week plus shipping time.
If you have a large order of inserts, give me a call or email & I'll give you the shipping price.
