I have to say, I'm absolutely bowled over by these Father's Day Pillow Covers Pillowcase for Dad (Dad)! They're everything my dad in his "World #1 Dad" shirt always dreamed of. The material is luxurious and soft Linen that makes the pillow feel extra cozy! But best of all, it was easy to surprise him with this gift because the invisible zipper made it so simple to exchange out one pillow cover for another (so sneaky!). Not only did he get a stylish upgrade but also an invisible wink from me ;) What's more, when we got closer together on Father's Day, he loved how perfect the size 17.3(L)*17.3(W) Inch fit into our family photo - like they were custom made just for us parents! Yup, this is definitely a must buy item if you want heartfelt hugs from your manly man of honor ;).
