Review on HONEYSEW Bobbins Machine15 30 2996 15PCS BOBBINS Sewing Set: High-Quality Bobbins for Seamless Stitching by Doris Tran

- Well I'm writing this before I actually *use* any of these spools but they are steel (magnetic) and come in a storage box as shown. The base is a thick foam material held on spools. The first time I had to pick them out, but then it's a little easier to put them back in and remove them. - I really appreciate this case because I'm only a casual sewer so I don't have any of the nifty "Professional Storage" stuff that Serios Sewers can have. So for me a good option for storing wound coils. - If anything negative happens while using it, I will edit this review; If I don't edit it in a few weeks they work lol!
