Aunque no son los más cómodos para llenar, su diseño ayuda que rápidamente tengas esferas perfectas. Ahorra espacio porque se pueden apilarBought these for the occasional whiskey drink but they've become my go to cube. They look cool and last about 2 hours. They pop right out of the mold and filling is a breeze. Great product.I just recently within thr last 6 months started getting into bourbon. So I bought tumblers and some crappy ice molds from Walmart but quickly became sick of the molds, they never kept water in and leaked all over. THESE however, are the PERFECT size for my Tumblers and do NOT leak, they are outstanding and have made my bourbon experiences much more enjoyable. The fact that 2 sets came in the packs make it so much better! Pretty sure I got the 2 inch molds.Love these. I purchased another brand with different construction, and they were terrible because they didn't seal for the freezing process. I purchased many more sets for family members. they are certainly fun, instead of the normal ice.I gifted this to friends this past Christmas-and everyone loved it!!They make huge ice cubes. Easy to use . Easy to clean .I love these ice cube trays BUT make sure the lids are snapped on tight!! I had a mess when the lids popped off as I was putting them in the freezer.I bought these because I thought it would be pretty cool to have ice balls. Well let me tell ya it is cool to have ice balls. Everyone wants my ice balls so much I hardly have enough to go around. Now even the neighbors want my ice balls. I have to hide my ice balls sometimes especially when its hot outside!!!the mould works well, tight fit on the tops with no spillage in the seams. will sometimes get a little overflow out the top when frozen because of water expansion so only fill to the line marked close to the top. can also be filled without the funnels but theyre a nice touch anyways.Top Eiswürfelform
