UgerlovWomen's Oversized Sweaters Batwing Sleeve Mock Neck Jumper Tops Chunky Knit Pullover Sweater

Are the sleeves long enough?

They say sweater is made of merino wool, is it really itchy?

Has anyone washed this sweater in a machine? The tag doesn’t say and the description says hand wash only and machine wash cold. Which is it?

Is the item stretchy ?
