Travel Folding Cup S/M/L Stainless Steel Cup Camp Keychain Design Retractable Telescopic Collapsible Cup(S)

The base is very sharp ! ... there is no actual way to know that it is locked in place ... had a tea and it heated up super quick ... the key ring broke in first five mins or maybe it was already broke . But will see how it goes

VERY HANDY PORTABLE CUP WHEN TRAVELLING AND CREATES LESS POLLUTION AS ITS REUSABLE COMPARED TO DISPOSIBLE CUPS.
