So I recently purchased 12 stickers so I will combine my review for all of them in this one rather than individually.
I already owned a few stickers from BTC, and overall I am impressed with the quality of their stickers.
The only reason I took a star off was because after applying the sticker to a water bottle and washed it in the dishwasher, it did bubble, which is strange because it never did this with my other stickers, I was able to remove most of the bubbling.
Overall I am happy with my purchase and would buy from them again.
