Review on ISTOYO Sublimation Double Walled Stainless Insulated by Doris Tran

These mason jars are of excellent quality, easy to sublimate in both the convection oven and mug press, and very charming. The only real downside is that they are more expensive than the competition. The quality of these glasses is excellent. They are durable, easy to remove and close with lids, well packaged. They came individually wrapped, which is also perfect as a gift. The straws have a durable feel and fit well in the lids. They're not sealed around the edges of the lid, but they're airtight, and since the lid has a hole for a straw, that's more than enough for me. What did I like best about this set that many others don't like? Additional heat shrink tubing included. I have purchased several sets of these glasses from different manufacturers and most come with a case for each glass. People with less experience or even people with more experience can easily damage packaging when heating. This set contains 10 wraps for 4 glasses. So if you accidentally burn or tear a wrap, you'll have a spare. the best deal, because at the current price of around $51 for a set of 4, that's not the case.
