Sieral30 Pcs Blank Sublimation Drawstring Bags Drawstring Backpack Bulk Heat Press Reusable Polyester Sublimation Bags Cinch Sackpack for Gym Sport DIY Craft, White

They are made really cheap, if you do sublimate on backpack be careful of when you use a heat press the black plastic corners and the strings will melt. 360° for 50 secs with a pillow heat cushion inside for best results

I guess you get what you pay for… these are super cheap and do not take sublimation at all. Even using a pressing pillow, low pressure. Total waste of money as I will not be able to use these at all

I read the reviews. A lot of people stated that the bags melted and are cheap. So, my first impression was hm they are cheap. But they are actually just see through. Use a heat press at 250 degrees max. If using an iron set it to polyester. I haven’t melted one yet! So far have tried HTV and have had great results. These are great promotional items.

I got them because I needed them to be in quickly and for a bunch of kids. They came in on time. The price was good. But they came in vacuum sealed and folded so there was a really hard crease down the middle which I tried to steam out but I ended up having to put them through the heat press. Unfortunately it took a few bags to get burned and the plastic strings and corners to melt before I changed heat presses from a swing press to a smaller cricut press. Anyhow, for the money I guess it was worth it but the material is thin and cheaply made, I would not buy again.

I sell a lot of sublimated items. These keychains are fantastic. Would definitely recommend them.

The drawstring bags are great for personal crafts and business.As a Boutique owner I was very impressed how excellent the sublimation and puff vinyl did on my bags. You do need to pay attention to heat press temp and timing not to burn your drawstrings.I press at 250 degress for 15 secs I had to play around to figure out getting the wrinkle out after that my designs came out great!! It's all about learning the material and how to use your heatpress correct for these bags. I will be buying more in future and I would like to see different colors please. 🤩

Very thin and see through on the white. Did not sublimate well at all, many faded areas. I tried 4 times using first the recommended heat temperature and time, then the temperature and time on the sublimation paper packet, then other suggested heat and ftimes and did not work at all for sublimation.

They subbed pretty well but they are very very thin. They had to be done at the perfect temperature and time. It is also difficult because of the strings and the bottom rings. Don’t think I would ever sell them
