Sleeve size does not change based on tumbler size selection.

We highly value the quality of the products we provide you. B-Grade sleeves are sleeves that didn’t pass our quality control checks because of damaged areas, imperfections from the manufacturing process or wrong sizing.

• This product is for SLEEVE ONLY products.

• Box includes FIVE random B-Grade sleeves.

• Hole size may vary.

• B-Grades are very much still usable but may need extra care. 
• Tumbler bundles are not available with the Mystery Box.

What about other brands or cups?

The sizes above fit the brands and sizes listed best, however they may still fit other brands/styles. Hole diameter for each size is listed to help you identify other brands/styles that could also fit.

Awesome deal!

I utterly love the randomness of what I get and it's such a awesome deal! Ita fun to see what I get and then I pushes me to think of a way tovuse the sleeves.

Awesome Deal

I love the B Grade box because I am always altering the sleeves so much, this is perfect. The surprise is fun and the assortment is great.

B Grade Sleeves

I wanted to get a surprise in sleeves at a great deal, so I ordered the Mystery Bundle! Loved it as I got some sleeves i was iffy about and now I have them and you can't really tell anything is wrong with them!


This was an amazing deal! I've never done any type of 3D tumbler so I thought I might as well get these B-grade sleeves to use as practice. There's hardly anything wrong with them - nothing that can't be fixed with a little creativity! Absolutely loved this and can't wait to create amazing tumblers!

  • Heat Sensitivity

    Our sleeves are sensitive to heat, so please don't leave them in your vehicles! Excessive heat can cause warping/shrinking so please be careful when torching! Your final coat should help mitigate these effects.
